https://notcve.org/view.php?id=CVE-2023-42755
A flaw was found in the IPv4 Resource Reservation Protocol (RSVP) classifier in the Linux kernel. The xprt pointer may go beyond the linear part of the skb, leading to an out-of-bounds read in the `rsvp_classify` function. This issue may allow a local user to crash the system and cause a denial of service. Se encontró una falla en el clasificador del IPv4 Resource Reservation Protocol (RSVP) en el kernel de Linux. El puntero xprt puede ir más allá de la parte lineal del skb, lo que lleva a una lectura fuera de límites en la función `rsvp_classify`. • https://access.redhat.com/errata/RHSA-2024:2950 https://access.redhat.com/errata/RHSA-2024:3138 https://access.redhat.com/security/cve/CVE-2023-42755 https://bugzilla.redhat.com/show_bug.cgi?id=2239847 https://lists.debian.org/debian-lts-announce/2023/10/msg00027.html https://lists.debian.org/debian-lts-announce/2024/01/msg00004.html https://seclists.org/oss-sec/2023/q3/229 • CWE-125: Out-of-bounds Read •

VP9 in libvpx before 1.13.1 mishandles widths, leading to a crash related to encoding. VP9 en libvpx anterior a 1.13.1 maneja mal las anchuras, lo que provoca un bloqueo relacionado con la codificación. A heap-based buffer overflow flaw was found in libvpx, a library used to process VP9 video codecs data. This issue occurs when processing certain specially formatted video data via a crafted HTML page, allowing an attacker to crash or remotely execute arbitrary code in an application, such as a web browser that is compiled with this library. • http://www.openwall.com/lists/oss-security/2023/09/30/4 https://bugzilla.redhat.com/show_bug.cgi?id=2241806 https://github.com/webmproject/libvpx/commit/263682c9a29395055f3b3afe2d97be1828a6223f https://github.com/webmproject/libvpx/commit/df9fd9d5b7325060b2b921558a1eb20ca7880937 https://github.com/webmproject/libvpx/compare/v1.13.0...v1.13.1 https://github.com/webmproject/libvpx/releases/tag/v1.13.1 https://lists.debian.org/debian-lts-announce/2023/10/msg00001.html https://lists.fedoraproject.org&#x • CWE-755: Improper Handling of Exceptional Conditions •

https://notcve.org/view.php?id=CVE-2023-42753
An array indexing vulnerability was found in the netfilter subsystem of the Linux kernel. A missing macro could lead to a miscalculation of the `h->nets` array offset, providing attackers with the primitive to arbitrarily increment/decrement a memory buffer out-of-bound. This issue may allow a local user to crash the system or potentially escalate their privileges on the system. Se encontró una vulnerabilidad de indexación de matrices en el subsistema netfilter del kernel de Linux. Una macro faltante podría provocar un error de cálculo del desplazamiento de la matriz `h->nets`, proporcionando a los atacantes la primitiva de incrementar/disminuir arbitrariamente un búfer de memoria fuera de límites. • http://packetstormsecurity.com/files/175963/Kernel-Live-Patch-Security-Notice-LSN-0099-1.html https://access.redhat.com/errata/RHSA-2023:7370 https://access.redhat.com/errata/RHSA-2023:7379 https://access.redhat.com/errata/RHSA-2023:7382 https://access.redhat.com/errata/RHSA-2023:7389 https://access.redhat.com/errata/RHSA-2023:7411 https://access.redhat.com/errata/RHSA-2023:7418 https://access.redhat.com/errata/RHSA-2023:7539 https://access.redhat.com/errata/RHSA-2023:7558 h • CWE-787: Out-of-bounds Write •

A vulnerability was found in PostgreSQL with the use of the MERGE command, which fails to test new rows against row security policies defined for UPDATE and SELECT. If UPDATE and SELECT policies forbid some rows that INSERT policies do not forbid, a user could store such rows. Se encontró una vulnerabilidad en PostgreSQL con el uso del comando MERGE, que no puede probar nuevas filas con las políticas de seguridad de filas definidas para ACTUALIZAR y SELECCIONAR. Si las políticas ACTUALIZAR y SELECCIONAR prohíben algunas filas que las políticas INSERTAR no prohíben, un usuario podría almacenar dichas filas. • https://access.redhat.com/errata/RHSA-2023:7785 https://access.redhat.com/errata/RHSA-2023:7883 https://access.redhat.com/errata/RHSA-2023:7884 https://access.redhat.com/errata/RHSA-2023:7885 https://access.redhat.com/security/cve/CVE-2023-39418 https://bugzilla.redhat.com/show_bug.cgi?id=2228112 https://git.postgresql.org/gitweb/?p=postgresql.git;a=commitdiff;h=cb2ae5741f2458a474ed3c31458d242e678ff229 https://security.netapp.com/advisory/ntap-20230915-0002 https://www.debian.org/security •
