| CVE-2021-3450 | 11 Fedoraproject, Freebsd, Mcafee and 8 more | 39 Fedora, Freebsd, Web Gateway and 36 more | 2024-09-17 | 7.4 High |
| The X509_V_FLAG_X509_STRICT flag enables additional security checks of the certificates present in a certificate chain. It is not set by default. Starting from OpenSSL version 1.1.1h a check to disallow certificates in the chain that have explicitly encoded elliptic curve parameters was added as an additional strict check. An error in the implementation of this check meant that the result of a previous check to confirm that certificates in the chain are valid CA certificates was overwritten. This effectively bypasses the check that non-CA certificates must not be able to issue other certificates. If a "purpose" has been configured then there is a subsequent opportunity for checks that the certificate is a valid CA. All of the named "purpose" values implemented in libcrypto perform this check. Therefore, where a purpose is set the certificate chain will still be rejected even when the strict flag has been used. A purpose is set by default in libssl client and server certificate verification routines, but it can be overridden or removed by an application. In order to be affected, an application must explicitly set the X509_V_FLAG_X509_STRICT verification flag and either not set a purpose for the certificate verification or, in the case of TLS client or server applications, override the default purpose. OpenSSL versions 1.1.1h and newer are affected by this issue. Users of these versions should upgrade to OpenSSL 1.1.1k. OpenSSL 1.0.2 is not impacted by this issue. Fixed in OpenSSL 1.1.1k (Affected 1.1.1h-1.1.1j). | ||||
| CVE-2022-2795 | 4 Debian, Fedoraproject, Isc and 1 more | 5 Debian Linux, Fedora, Bind and 2 more | 2024-09-17 | 5.3 Medium |
| By flooding the target resolver with queries exploiting this flaw an attacker can significantly impair the resolver's performance, effectively denying legitimate clients access to the DNS resolution service. | ||||
| CVE-2021-21703 | 6 Debian, Fedoraproject, Netapp and 3 more | 7 Debian Linux, Fedora, Clustered Data Ontap and 4 more | 2024-09-17 | 7.8 High |
| In PHP versions 7.3.x up to and including 7.3.31, 7.4.x below 7.4.25 and 8.0.x below 8.0.12, when running PHP FPM SAPI with main FPM daemon process running as root and child worker processes running as lower-privileged users, it is possible for the child processes to access memory shared with the main process and write to it, modifying it in a way that would cause the root process to conduct invalid memory reads and writes, which can be used to escalate privileges from local unprivileged user to the root user. | ||||
| CVE-2022-38178 | 5 Debian, Fedoraproject, Isc and 2 more | 8 Debian Linux, Fedora, Bind and 5 more | 2024-09-17 | 7.5 High |
| By spoofing the target resolver with responses that have a malformed EdDSA signature, an attacker can trigger a small memory leak. It is possible to gradually erode available memory to the point where named crashes for lack of resources. | ||||
| CVE-2020-1971 | 9 Debian, Fedoraproject, Netapp and 6 more | 55 Debian Linux, Fedora, Active Iq Unified Manager and 52 more | 2024-09-17 | 5.9 Medium |
| The X.509 GeneralName type is a generic type for representing different types of names. One of those name types is known as EDIPartyName. OpenSSL provides a function GENERAL_NAME_cmp which compares different instances of a GENERAL_NAME to see if they are equal or not. This function behaves incorrectly when both GENERAL_NAMEs contain an EDIPARTYNAME. A NULL pointer dereference and a crash may occur leading to a possible denial of service attack. OpenSSL itself uses the GENERAL_NAME_cmp function for two purposes: 1) Comparing CRL distribution point names between an available CRL and a CRL distribution point embedded in an X509 certificate 2) When verifying that a timestamp response token signer matches the timestamp authority name (exposed via the API functions TS_RESP_verify_response and TS_RESP_verify_token) If an attacker can control both items being compared then that attacker could trigger a crash. For example if the attacker can trick a client or server into checking a malicious certificate against a malicious CRL then this may occur. Note that some applications automatically download CRLs based on a URL embedded in a certificate. This checking happens prior to the signatures on the certificate and CRL being verified. OpenSSL's s_server, s_client and verify tools have support for the "-crl_download" option which implements automatic CRL downloading and this attack has been demonstrated to work against those tools. Note that an unrelated bug means that affected versions of OpenSSL cannot parse or construct correct encodings of EDIPARTYNAME. However it is possible to construct a malformed EDIPARTYNAME that OpenSSL's parser will accept and hence trigger this attack. All OpenSSL 1.1.1 and 1.0.2 versions are affected by this issue. Other OpenSSL releases are out of support and have not been checked. Fixed in OpenSSL 1.1.1i (Affected 1.1.1-1.1.1h). Fixed in OpenSSL 1.0.2x (Affected 1.0.2-1.0.2w). | ||||
| CVE-2018-3846 | 2 Fedoraproject, Nasa | 2 Fedora, Cfitsio | 2024-09-17 | 8.8 High |

| Potential floating point value injection in all supported CPU products, in conjunction with software vulnerabilities relating to speculative execution with incorrect floating point results, may cause the use of incorrect data from FPVI and may result in data leakage. | ||||
| CVE-2022-24919 | 3 Debian, Fedoraproject, Zabbix | 3 Debian Linux, Fedora, Frontend | 2024-09-17 | 3.7 Low |
| An authenticated user can create a link with reflected Javascript code inside it for graphs’ page and send it to other users. The payload can be executed only with a known CSRF token value of the victim, which is changed periodically and is difficult to predict. Malicious code has access to all the same objects as the rest of the web page and can make arbitrary modifications to the contents of the page being displayed to a victim during social engineering attacks. | ||||
| CVE-2020-8835 | 4 Canonical, Fedoraproject, Linux and 1 more | 47 Ubuntu Linux, Fedora, Linux Kernel and 44 more | 2024-09-17 | 7.8 High |
| In the Linux kernel 5.5.0 and newer, the bpf verifier (kernel/bpf/verifier.c) did not properly restrict the register bounds for 32-bit operations, leading to out-of-bounds reads and writes in kernel memory. The vulnerability also affects the Linux 5.4 stable series, starting with v5.4.7, as the introducing commit was backported to that branch. This vulnerability was fixed in 5.6.1, 5.5.14, and 5.4.29. (issue is aka ZDI-CAN-10780) | ||||
| CVE-2022-3080 | 3 Fedoraproject, Isc, Redhat | 3 Fedora, Bind, Enterprise Linux | 2024-09-17 | 7.5 High |
| By sending specific queries to the resolver, an attacker can cause named to crash. | ||||
| CVE-2018-8786 | 5 Canonical, Debian, Fedoraproject and 2 more | 11 Ubuntu Linux, Debian Linux, Fedora and 8 more | 2024-09-17 | 9.8 Critical |
| FreeRDP prior to version 2.0.0-rc4 contains an Integer Truncation that leads to a Heap-Based Buffer Overflow in function update_read_bitmap_update() and results in a memory corruption and probably even a remote code execution. | ||||
| CVE-2019-11044 | 3 Fedoraproject, Php, Tenable | 3 Fedora, Php, Securitycenter | 2024-09-17 | 3.7 Low |
| In PHP versions 7.2.x below 7.2.26, 7.3.x below 7.3.13 and 7.4.0 on Windows, PHP link() function accepts filenames with embedded \0 byte and treats them as terminating at that byte. This could lead to security vulnerabilities, e.g. in applications checking paths that the code is allowed to access. | ||||
| CVE-2018-3849 | 2 Fedoraproject, Nasa | 2 Fedora, Cfitsio | 2024-09-17 | 8.8 High |
| In the ffghtb function in NASA CFITSIO 3.42, specially crafted images parsed via the library can cause a stack-based buffer overflow overwriting arbitrary data. An attacker can deliver an FIT image to trigger this vulnerability and potentially gain code execution. | ||||
| CVE-2019-3463 | 4 Canonical, Debian, Fedoraproject and 1 more | 4 Ubuntu Linux, Debian Linux, Fedora and 1 more | 2024-09-17 | 9.8 Critical |
| Insufficient sanitization of arguments passed to rsync can bypass the restrictions imposed by rssh, a restricted shell that should restrict users to perform only rsync operations, resulting in the execution of arbitrary shell commands. | ||||
| CVE-2021-23351 | 2 Fedoraproject, Go-proxyproto Project | 2 Fedora, Go-proxyproto | 2024-09-17 | 4.4 Medium |
| The package github.com/pires/go-proxyproto before 0.5.0 are vulnerable to Denial of Service (DoS) via the parseVersion1() function. The reader in this package is a default bufio.Reader wrapping a net.Conn. It will read from the connection until it finds a newline. Since no limits are implemented in the code, a deliberately malformed V1 header could be used to exhaust memory in a server process using this code - and create a DoS. This can be exploited by sending a stream starting with PROXY and continuing to send data (which does not contain a newline) until the target stops acknowledging. The risk here is small, because only trusted sources should be allowed to send proxy protocol headers. | ||||
| CVE-2020-28463 | 2 Fedoraproject, Reportlab | 2 Fedora, Reportlab | 2024-09-17 | 6.5 Medium |
| All versions of package reportlab are vulnerable to Server-side Request Forgery (SSRF) via img tags. In order to reduce risk, use trustedSchemes & trustedHosts (see in Reportlab's documentation) Steps to reproduce by Karan Bamal: 1. Download and install the latest package of reportlab 2. Go to demos -> odyssey -> dodyssey 3. In the text file odyssey.txt that needs to be converted to pdf inject <img src="http://127.0.0.1:5000" valign="top"/> 4. Create a nc listener nc -lp 5000 5. Run python3 dodyssey.py 6. You will get a hit on your nc showing we have successfully proceded to send a server side request 7. dodyssey.py will show error since there is no img file on the url, but we are able to do SSRF | ||||
