CVSS: 7.5EPSS: 0%CPEs: 5EXPL: 2CVE-2024-0567 – Gnutls: rejects certificate chain with distributed trust
https://notcve.org/view.php?id=CVE-2024-0567
A vulnerability was found in GnuTLS, where a cockpit (which uses gnuTLS) rejects a certificate chain with distributed trust. This issue occurs when validating a certificate chain with cockpit-certificate-ensure. This flaw allows an unauthenticated, remote client or attacker to initiate a denial of service attack. Se encontró una vulnerabilidad en GnuTLS, donde una cabina (que usa gnuTLS) rechaza una cadena de certificados con confianza distribuida. Este problema ocurre al validar una cadena de certificados con cockpit-certificate-ensure. • http://www.openwall.com/lists/oss-security/2024/01/19/3 https://access.redhat.com/errata/RHSA-2024:0533 https://access.redhat.com/errata/RHSA-2024:1082 https://access.redhat.com/errata/RHSA-2024:1383 https://access.redhat.com/errata/RHSA-2024:2094 https://access.redhat.com/security/cve/CVE-2024-0567 https://bugzilla.redhat.com/show_bug.cgi?id=2258544 https://gitlab.com/gnutls/gnutls/-/issues/1521 https://lists.fedoraproject.org/archives/list/package-announce@lists. • CWE-347: Improper Verification of Cryptographic Signature •
CVSS: 9.8EPSS: 2%CPEs: 12EXPL: 1CVE-2023-5178 – Kernel: use after free in nvmet_tcp_free_crypto in nvme
https://notcve.org/view.php?id=CVE-2023-5178
A use-after-free vulnerability was found in drivers/nvme/target/tcp.c` in `nvmet_tcp_free_crypto` due to a logical bug in the NVMe/TCP subsystem in the Linux kernel. This issue may allow a malicious user to cause a use-after-free and double-free problem, which may permit remote code execution or lead to local privilege escalation. Se encontró una vulnerabilidad de use-after-free en drivers/nvme/target/tcp.c` en `nvmet_tcp_free_crypto` debido a un error lógico en el subsistema NVMe-oF/TCP en el kernel de Linux. Este problema puede permitir que un usuario malintencionado cause un problema de use-after-free y double-free, lo que puede permitir la ejecución remota de código o provocar una escalada de privilegios locales en caso de que el atacante ya tenga privilegios locales. • https://github.com/rockrid3r/CVE-2023-5178 https://access.redhat.com/errata/RHSA-2023:7370 https://access.redhat.com/errata/RHSA-2023:7379 https://access.redhat.com/errata/RHSA-2023:7418 https://access.redhat.com/errata/RHSA-2023:7548 https://access.redhat.com/errata/RHSA-2023:7549 https://access.redhat.com/errata/RHSA-2023:7551 https://access.redhat.com/errata/RHSA-2023:7554 https://access.redhat.com/errata/RHSA-2023:7557 https://access.redhat.com/errata/RHSA-2023 • CWE-416: Use After Free •

CVSS: 9.8EPSS: 0%CPEs: 14EXPL: 8CVE-2023-38545 – curl: heap based buffer overflow in the SOCKS5 proxy handshake
https://notcve.org/view.php?id=CVE-2023-38545
This flaw makes curl overflow a heap based buffer in the SOCKS5 proxy handshake. When curl is asked to pass along the host name to the SOCKS5 proxy to allow that to resolve the address instead of it getting done by curl itself, the maximum length that host name can be is 255 bytes. If the host name is detected to be longer, curl switches to local name resolving and instead passes on the resolved address only. Due to this bug, the local variable that means "let the host resolve the name" could get the wrong value during a slow SOCKS5 handshake, and contrary to the intention, copy the too long host name to the target buffer instead of copying just the resolved address there. The target buffer being a heap based buffer, and the host name coming from the URL that curl has been told to operate with. Esta falla hace que curl desborde un búfer basado en el protocolo de enlace del proxy SOCKS5. Cuando se le pide a curl que pase el nombre de host al proxy SOCKS5 para permitir que resuelva la dirección en lugar de que lo haga curl mismo, la longitud máxima que puede tener el nombre de host es 255 bytes. Si se detecta que el nombre de host es más largo, curl cambia a la resolución de nombres local y en su lugar pasa solo la dirección resuelta. • https://github.com/d0rb/CVE-2023-38545 https://github.com/vanigori/CVE-2023-38545-sample https://github.com/UTsweetyfish/CVE-2023-38545 https://github.com/fatmo666/CVE-2023-38545-libcurl-SOCKS5-heap-buffer-overflow https://github.com/imfht/CVE-2023-38545 https://github.com/bcdannyboy/CVE-2023-38545 https://github.com/dbrugman/CVE-2023-38545-POC https://github.com/Yang-Shun-Yu/CVE-2023-38545 http://seclists.org/fulldisclosure/2024/Jan/34 http://seclists.org/fulldisclosure • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-787: Out-of-bounds Write •
