| The SSH transport protocol with certain OpenSSH extensions, found in OpenSSH before 9.6 and other products, allows remote attackers to bypass integrity checks such that some packets are omitted (from the extension negotiation message), and a client and server may consequently end up with a connection for which some security features have been downgraded or disabled, aka a Terrapin attack. This occurs because the SSH Binary Packet Protocol (BPP), implemented by these extensions, mishandles the handshake phase and mishandles use of sequence numbers. For example, there is an effective attack against SSH's use of ChaCha20-Poly1305 (and CBC with Encrypt-then-MAC). The bypass occurs in chacha20-poly1305@openssh.com and (if CBC is used) the -etm@openssh.com MAC algorithms.

| CVE-2023-46136 | 2 Palletsprojects, Redhat | 3 Werkzeug, Openshift Ironic, Openstack | 2024-08-02 | 8 High |
| Werkzeug is a comprehensive WSGI web application library. If an upload of a file that starts with CR or LF and then is followed by megabytes of data without these characters: all of these bytes are appended chunk by chunk into internal bytearray and lookup for boundary is performed on growing buffer. This allows an attacker to cause a denial of service by sending crafted multipart data to an endpoint that will parse it. The amount of CPU time required can block worker processes from handling legitimate requests. This vulnerability has been patched in version 3.0.1. | ||||
| CVE-2023-46118 | 2 Redhat, Vmware | 2 Openstack, Rabbitmq | 2024-08-02 | 4.9 Medium |
| RabbitMQ is a multi-protocol messaging and streaming broker. HTTP API did not enforce an HTTP request body limit, making it vulnerable for denial of service (DoS) attacks with very large messages. An authenticated user with sufficient credentials can publish a very large messages over the HTTP API and cause target node to be terminated by an "out-of-memory killer"-like mechanism. This vulnerability has been patched in versions 3.11.24 and 3.12.7. | ||||
| CVE-2023-45287 | 2 Golang, Redhat | 11 Go, Enterprise Linux, Migration Toolkit Applications and 8 more | 2024-08-02 | 7.5 High |
| Before Go 1.20, the RSA based TLS key exchanges used the math/big library, which is not constant time. RSA blinding was applied to prevent timing attacks, but analysis shows this may not have been fully effective. In particular it appears as if the removal of PKCS#1 padding may leak timing information, which in turn could be used to recover session key bits. In Go 1.20, the crypto/tls library switched to a fully constant time RSA implementation, which we do not believe exhibits any timing side channels. | ||||
| CVE-2023-41419 | 2 Gevent, Redhat | 7 Gevent, Enterprise Linux, Openstack and 4 more | 2024-08-02 | 9.8 Critical |
| An issue in Gevent before version 23.9.0 allows a remote attacker to escalate privileges via a crafted script to the WSGIServer component. | ||||
| CVE-2023-39326 | 2 Golang, Redhat | 20 Go, Ansible Automation Platform, Cryostat and 17 more | 2024-08-02 | 5.3 Medium |
| A malicious HTTP sender can use chunk extensions to cause a receiver reading from a request or response body to read many more bytes from the network than are in the body. A malicious HTTP client can further exploit this to cause a server to automatically read a large amount of data (up to about 1GiB) when a handler fails to read the entire body of a request. Chunk extensions are a little-used HTTP feature which permit including additional metadata in a request or response body sent using the chunked encoding. The net/http chunked encoding reader discards this metadata. A sender can exploit this by inserting a large metadata segment with each byte transferred. The chunk reader now produces an error if the ratio of real body to encoded bytes grows too small. | ||||
| CVE-2023-39325 | 4 Fedoraproject, Golang, Netapp and 1 more | 53 Fedora, Go, Http2 and 50 more | 2024-08-02 | 7.5 High |
| A malicious HTTP/2 client which rapidly creates requests and immediately resets them can cause excessive server resource consumption. While the total number of requests is bounded by the http2.Server.MaxConcurrentStreams setting, resetting an in-progress request allows the attacker to create a new request while the existing one is still executing. With the fix applied, HTTP/2 servers now bound the number of simultaneously executing handler goroutines to the stream concurrency limit (MaxConcurrentStreams). New requests arriving when at the limit (which can only happen after the client has reset an existing, in-flight request) will be queued until a handler exits. If the request queue grows too large, the server will terminate the connection. This issue is also fixed in golang.org/x/net/http2 for users manually configuring HTTP/2. The default stream concurrency limit is 250 streams (requests) per HTTP/2 connection. This value may be adjusted using the golang.org/x/net/http2 package; see the Server.MaxConcurrentStreams setting and the ConfigureServer function. | ||||
| CVE-2023-36053 | 4 Debian, Djangoproject, Fedoraproject and 1 more | 8 Debian Linux, Django, Fedora and 5 more | 2024-08-02 | 7.5 High |
| In Django 3.2 before 3.2.20, 4 before 4.1.10, and 4.2 before 4.2.3, EmailValidator and URLValidator are subject to a potential ReDoS (regular expression denial of service) attack via a very large number of domain name labels of emails and URLs. | ||||
| CVE-2023-32082 | 2 Etcd, Redhat | 2 Etcd, Openstack | 2024-08-02 | 3.1 Low |
| etcd is a distributed key-value store for the data of a distributed system. Prior to versions 3.4.26 and 3.5.9, the LeaseTimeToLive API allows access to key names (not value) associated to a lease when `Keys` parameter is true, even a user doesn't have read permission to the keys. The impact is limited to a cluster which enables auth (RBAC). Versions 3.4.26 and 3.5.9 fix this issue. There are no known workarounds. | ||||
| CVE-2023-30861 | 2 Palletsprojects, Redhat | 5 Flask, Openshift Ironic, Openstack and 2 more | 2024-08-02 | 7.5 High |
| Flask is a lightweight WSGI web application framework. When all of the following conditions are met, a response containing data intended for one client may be cached and subsequently sent by the proxy to other clients. If the proxy also caches `Set-Cookie` headers, it may send one client's `session` cookie to other clients. The severity depends on the application's use of the session and the proxy's behavior regarding cookies. The risk depends on all these conditions being met. 1. The application must be hosted behind a caching proxy that does not strip cookies or ignore responses with cookies. 2. The application sets `session.permanent = True` 3. The application does not access or modify the session at any point during a request. 4. `SESSION_REFRESH_EACH_REQUEST` enabled (the default). 5. The application does not set a `Cache-Control` header to indicate that a page is private or should not be cached. This happens because vulnerable versions of Flask only set the `Vary: Cookie` header when the session is accessed or modified, not when it is refreshed (re-sent to update the expiration) without being accessed or modified. This issue has been fixed in versions 2.3.2 and 2.2.5. | ||||
| CVE-2023-29400 | 2 Golang, Redhat | 22 Go, Acm, Advanced Cluster Security and 19 more | 2024-08-02 | 7.3 High |
| Templates containing actions in unquoted HTML attributes (e.g. "attr={{.}}") executed with empty input can result in output with unexpected results when parsed due to HTML normalization rules. This may allow injection of arbitrary attributes into tags. | ||||
| CVE-2023-25577 | 2 Palletsprojects, Redhat | 5 Werkzeug, Openshift, Openshift Ironic and 2 more | 2024-08-02 | 7.5 High |
| Werkzeug is a comprehensive WSGI web application library. Prior to version 2.2.3, Werkzeug's multipart form data parser will parse an unlimited number of parts, including file parts. Parts can be a small amount of bytes, but each requires CPU time to parse and may use more memory as Python data. If a request can be made to an endpoint that accesses `request.data`, `request.form`, `request.files`, or `request.get_data(parse_form_data=False)`, it can cause unexpectedly high resource usage. This allows an attacker to cause a denial of service by sending crafted multipart data to an endpoint that will parse it. The amount of CPU time required can block worker processes from handling legitimate requests. The amount of RAM required can trigger an out of memory kill of the process. Unlimited file parts can use up memory and file handles. If many concurrent requests are sent continuously, this can exhaust or kill all available workers. Version 2.2.3 contains a patch for this issue. | ||||
| CVE-2023-24534 | 2 Golang, Redhat | 22 Go, Advanced Cluster Security, Ansible Automation Platform and 19 more | 2024-08-02 | 7.5 High |
| HTTP and MIME header parsing can allocate large amounts of memory, even when parsing small inputs, potentially leading to a denial of service. Certain unusual patterns of input data can cause the common function used to parse HTTP and MIME headers to allocate substantially more memory than required to hold the parsed headers. An attacker can exploit this behavior to cause an HTTP server to allocate large amounts of memory from a small request, potentially leading to memory exhaustion and a denial of service. With fix, header parsing now correctly allocates only the memory required to hold parsed headers. | ||||
| CVE-2023-24536 | 2 Golang, Redhat | 19 Go, Advanced Cluster Security, Ansible Automation Platform and 16 more | 2024-08-02 | 7.5 High |
| Multipart form parsing can consume large amounts of CPU and memory when processing form inputs containing very large numbers of parts. This stems from several causes: 1. mime/multipart.Reader.ReadForm limits the total memory a parsed multipart form can consume. ReadForm can undercount the amount of memory consumed, leading it to accept larger inputs than intended. 2. Limiting total memory does not account for increased pressure on the garbage collector from large numbers of small allocations in forms with many parts. 3. ReadForm can allocate a large number of short-lived buffers, further increasing pressure on the garbage collector. The combination of these factors can permit an attacker to cause an program that parses multipart forms to consume large amounts of CPU and memory, potentially resulting in a denial of service. This affects programs that use mime/multipart.Reader.ReadForm, as well as form parsing in the net/http package with the Request methods FormFile, FormValue, ParseMultipartForm, and PostFormValue. With fix, ReadForm now does a better job of estimating the memory consumption of parsed forms, and performs many fewer short-lived allocations. In addition, the fixed mime/multipart.Reader imposes the following limits on the size of parsed forms: 1. Forms parsed with ReadForm may contain no more than 1000 parts. This limit may be adjusted with the environment variable GODEBUG=multipartmaxparts=. 2. Form parts parsed with NextPart and NextRawPart may contain no more than 10,000 header fields. In addition, forms parsed with ReadForm may contain no more than 10,000 header fields across all parts. This limit may be adjusted with the environment variable GODEBUG=multipartmaxheaders=. | ||||
| CVE-2023-24537 | 2 Golang, Redhat | 21 Go, Advanced Cluster Security, Ansible Automation Platform and 18 more | 2024-08-02 | 7.5 High |
| Calling any of the Parse functions on Go source code which contains //line directives with very large line numbers can cause an infinite loop due to integer overflow. | ||||
| CVE-2023-24539 | 2 Golang, Redhat | 22 Go, Acm, Advanced Cluster Security and 19 more | 2024-08-02 | 7.3 High |
| Angle brackets (<>) are not considered dangerous characters when inserted into CSS contexts. Templates containing multiple actions separated by a '/' character can result in unexpectedly closing the CSS context and allowing for injection of unexpected HTML, if executed with untrusted input. | ||||
| CVE-2023-24532 | 2 Golang, Redhat | 10 Go, Enterprise Linux, Migration Toolkit Applications and 7 more | 2024-08-02 | 5.3 Medium |
| The ScalarMult and ScalarBaseMult methods of the P256 Curve may return an incorrect result if called with some specific unreduced scalars (a scalar larger than the order of the curve). This does not impact usages of crypto/ecdsa or crypto/ecdh. | ||||
| CVE-2023-23934 | 2 Palletsprojects, Redhat | 2 Werkzeug, Openstack | 2024-08-02 | 2.6 Low |
| Werkzeug is a comprehensive WSGI web application library. Browsers may allow "nameless" cookies that look like `=value` instead of `key=value`. A vulnerable browser may allow a compromised application on an adjacent subdomain to exploit this to set a cookie like `=__Host-test=bad` for another subdomain. Werkzeug prior to 2.2.3 will parse the cookie `=__Host-test=bad` as __Host-test=bad`. If a Werkzeug application is running next to a vulnerable or malicious subdomain which sets such a cookie using a vulnerable browser, the Werkzeug application will see the bad cookie value but the valid cookie key. The issue is fixed in Werkzeug 2.2.3. | ||||
| CVE-2023-5366 | 2 Openvswitch, Redhat | 7 Openvswitch, Enterprise Linux, Fast Datapath and 4 more | 2024-08-02 | 7.1 High |
| A flaw was found in Open vSwitch that allows ICMPv6 Neighbor Advertisement packets between virtual machines to bypass OpenFlow rules. This issue may allow a local attacker to create specially crafted packets with a modified or spoofed target IP address field that can redirect ICMPv6 traffic to arbitrary IP addresses. | ||||
| CVE-2023-3354 | 3 Fedoraproject, Qemu, Redhat | 10 Fedora, Qemu, Advanced Virtualization and 7 more | 2024-08-02 | 7.5 High |
| A flaw was found in the QEMU built-in VNC server. When a client connects to the VNC server, QEMU checks whether the current number of connections crosses a certain threshold and if so, cleans up the previous connection. If the previous connection happens to be in the handshake phase and fails, QEMU cleans up the connection again, resulting in a NULL pointer dereference issue. This could allow a remote unauthenticated client to cause a denial of service. | ||||
