| CVE-2023-2650 | 3 Debian, Openssl, Redhat | 5 Debian Linux, Openssl, Enterprise Linux and 2 more | 2024-08-02 | 6.5 Medium |
| Issue summary: Processing some specially crafted ASN.1 object identifiers or data containing them may be very slow. Impact summary: Applications that use OBJ_obj2txt() directly, or use any of the OpenSSL subsystems OCSP, PKCS7/SMIME, CMS, CMP/CRMF or TS with no message size limit may experience notable to very long delays when processing those messages, which may lead to a Denial of Service. An OBJECT IDENTIFIER is composed of a series of numbers - sub-identifiers - most of which have no size limit. OBJ_obj2txt() may be used to translate an ASN.1 OBJECT IDENTIFIER given in DER encoding form (using the OpenSSL type ASN1_OBJECT) to its canonical numeric text form, which are the sub-identifiers of the OBJECT IDENTIFIER in decimal form, separated by periods. When one of the sub-identifiers in the OBJECT IDENTIFIER is very large (these are sizes that are seen as absurdly large, taking up tens or hundreds of KiBs), the translation to a decimal number in text may take a very long time. The time complexity is O(n^2) with 'n' being the size of the sub-identifiers in bytes (*). With OpenSSL 3.0, support to fetch cryptographic algorithms using names / identifiers in string form was introduced. This includes using OBJECT IDENTIFIERs in canonical numeric text form as identifiers for fetching algorithms. Such OBJECT IDENTIFIERs may be received through the ASN.1 structure AlgorithmIdentifier, which is commonly used in multiple protocols to specify what cryptographic algorithm should be used to sign or verify, encrypt or decrypt, or digest passed data. Applications that call OBJ_obj2txt() directly with untrusted data are affected, with any version of OpenSSL. If the use is for the mere purpose of display, the severity is considered low. In OpenSSL 3.0 and newer, this affects the subsystems OCSP, PKCS7/SMIME, CMS, CMP/CRMF or TS. It also impacts anything that processes X.509 certificates, including simple things like verifying its signature. The impact on TLS is relatively low, because all versions of OpenSSL have a 100KiB limit on the peer's certificate chain. Additionally, this only impacts clients, or servers that have explicitly enabled client authentication. In OpenSSL 1.1.1 and 1.0.2, this only affects displaying diverse objects, such as X.509 certificates. This is assumed to not happen in such a way that it would cause a Denial of Service, so these versions are considered not affected by this issue in such a way that it would be cause for concern, and the severity is therefore considered low. | ||||

| CVE-2023-2491 | 2 Gnu, Redhat | 5 Emacs, Enterprise Linux, Enterprise Linux Eus and 2 more | 2024-08-02 | 7.8 High |
| A flaw was found in the Emacs text editor. Processing a specially crafted org-mode code with the "org-babel-execute:latex" function in ob-latex.el can result in arbitrary command execution. This CVE exists because of a CVE-2023-28617 security regression for the emacs package in Red Hat Enterprise Linux 8.8 and Red Hat Enterprise Linux 9.2. | ||||
| CVE-2023-2455 | 3 Fedoraproject, Postgresql, Redhat | 9 Fedora, Postgresql, Enterprise Linux and 6 more | 2024-08-02 | 5.4 Medium |
| Row security policies disregard user ID changes after inlining; PostgreSQL could permit incorrect policies to be applied in certain cases where role-specific policies are used and a given query is planned under one role and then executed under other roles. This scenario can happen under security definer functions or when a common user and query is planned initially and then re-used across multiple SET ROLEs. Applying an incorrect policy may permit a user to complete otherwise-forbidden reads and modifications. This affects only databases that have used CREATE POLICY to define a row security policy. | ||||
| CVE-2023-2454 | 3 Fedoraproject, Postgresql, Redhat | 9 Fedora, Postgresql, Enterprise Linux and 6 more | 2024-08-02 | 7.2 High |
| schema_element defeats protective search_path changes; It was found that certain database calls in PostgreSQL could permit an authed attacker with elevated database-level privileges to execute arbitrary code. | ||||
| CVE-2023-2422 | 1 Redhat | 6 Enterprise Linux, Keycloak, Openshift Container Platform and 3 more | 2024-08-02 | 5.5 Medium |
| A flaw was found in Keycloak. A Keycloak server configured to support mTLS authentication for OAuth/OpenID clients does not properly verify the client certificate chain. A client that possesses a proper certificate can authorize itself as any other client, therefore, access data that belongs to other clients. | ||||
| CVE-2023-2319 | 2 Clusterlabs, Redhat | 4 Pcs, Enterprise Linux, Enterprise Linux High Availability and 1 more | 2024-08-02 | 9.8 Critical |
| It was discovered that an update for PCS package in RHBA-2023:2151 erratum released as part of Red Hat Enterprise Linux 9.2 failed to include the fix for the Webpack issue CVE-2023-28154 (for PCS package), which was previously addressed in Red Hat Enterprise Linux 9.1 via erratum RHSA-2023:1591. The CVE-2023-2319 was assigned to that Red Hat specific security regression in Red Hat Enterprise Linux 9.2. | ||||
| CVE-2023-2295 | 2 Libreswan, Redhat | 5 Libreswan, Enterprise Linux, Enterprise Linux Eus and 2 more | 2024-08-02 | 7.5 High |
| A vulnerability was found in the libreswan library. This security issue occurs when an IKEv1 Aggressive Mode packet is received with only unacceptable crypto algorithms, and the response packet is not sent with a zero responder SPI. When a subsequent packet is received where the sender reuses the libreswan responder SPI as its own initiator SPI, the pluto daemon state machine crashes. No remote code execution is possible. This CVE exists because of a CVE-2023-30570 security regression for libreswan package in Red Hat Enterprise Linux 8.8 and Red Hat Enterprise Linux 9.2. | ||||
| CVE-2023-2269 | 5 Debian, Fedoraproject, Linux and 2 more | 14 Debian Linux, Fedora, Linux Kernel and 11 more | 2024-08-02 | 4.4 Medium |
| A denial of service problem was found, due to a possible recursive locking scenario, resulting in a deadlock in table_clear in drivers/md/dm-ioctl.c in the Linux Kernel Device Mapper-Multipathing sub-component. | ||||
| CVE-2023-2283 | 3 Fedoraproject, Libssh, Redhat | 4 Fedora, Libssh, Enterprise Linux and 1 more | 2024-08-02 | 6.5 Medium |
| A vulnerability was found in libssh, where the authentication check of the connecting client can be bypassed in the`pki_verify_data_signature` function in memory allocation problems. This issue may happen if there is insufficient memory or the memory usage is limited. The problem is caused by the return value `rc,` which is initialized to SSH_ERROR and later rewritten to save the return value of the function call `pki_key_check_hash_compatible.` The value of the variable is not changed between this point and the cryptographic verification. Therefore any error between them calls `goto error` returning SSH_OK. | ||||
| CVE-2023-2255 | 3 Debian, Libreoffice, Redhat | 3 Debian Linux, Libreoffice, Enterprise Linux | 2024-08-02 | 5.3 Medium |
| Improper access control in editor components of The Document Foundation LibreOffice allowed an attacker to craft a document that would cause external links to be loaded without prompt. In the affected versions of LibreOffice documents that used "floating frames" linked to external files, would load the contents of those frames without prompting the user for permission to do so. This was inconsistent with the treatment of other linked content in LibreOffice. This issue affects: The Document Foundation LibreOffice 7.4 versions prior to 7.4.7; 7.5 versions prior to 7.5.3. | ||||
| CVE-2023-2235 | 2 Linux, Redhat | 4 Linux Kernel, Enterprise Linux, Rhel Eus and 1 more | 2024-08-02 | 7.8 High |
| A use-after-free vulnerability in the Linux Kernel Performance Events system can be exploited to achieve local privilege escalation. The perf_group_detach function did not check the event's siblings' attach_state before calling add_event_to_groups(), but remove_on_exec made it possible to call list_del_event() on before detaching from their group, making it possible to use a dangling pointer causing a use-after-free vulnerability. We recommend upgrading past commit fd0815f632c24878e325821943edccc7fde947a2. | ||||
| CVE-2023-2203 | 2 Redhat, Webkitgtk | 5 Enterprise Linux, Enterprise Linux Eus, Enterprise Linux Server Aus and 2 more | 2024-08-02 | 8.8 High |
| A flaw was found in the WebKitGTK package. An improper input validation issue may lead to a use-after-free vulnerability. This flaw allows attackers with network access to pass specially crafted web content files, causing a denial of service or arbitrary code execution. This CVE exists because of a CVE-2023-28205 security regression for the WebKitGTK package in Red Hat Enterprise Linux 8.8 and Red Hat Enterprise Linux 9.2. | ||||
| CVE-2023-2194 | 3 Fedoraproject, Linux, Redhat | 5 Fedora, Linux Kernel, Enterprise Linux and 2 more | 2024-08-02 | 6.7 Medium |
