CVE-2023-4911 – GNU C Library Buffer Overflow Vulnerability
https://notcve.org/view.php?id=CVE-2023-4911
A buffer overflow was discovered in the GNU C Library's dynamic loader ld.so while processing the GLIBC_TUNABLES environment variable. This issue could allow a local attacker to use maliciously crafted GLIBC_TUNABLES environment variables when launching binaries with SUID permission to execute code with elevated privileges. Se descubrió un desbordamiento del búfer en el cargador dinámico ld.so de la librería GNU C mientras se procesaba la variable de entorno GLIBC_TUNABLES. Este problema podría permitir que un atacante local utilice variables de entorno GLIBC_TUNABLES manipuladas con fines malintencionados al iniciar archivos binarios con permiso SUID para ejecutar código con privilegios elevados. Dubbed Looney Tunables, Qualys discovered a buffer overflow vulnerability in the glibc dynamic loader's processing of the GLIBC_TUNABLES environment variable. • https://github.com/leesh3288/CVE-2023-4911 https://github.com/ruycr4ft/CVE-2023-4911 https://github.com/guffre/CVE-2023-4911 https://github.com/NishanthAnand21/CVE-2023-4911-PoC https://github.com/RickdeJager/CVE-2023-4911 https://github.com/hadrian3689/looney-tunables-CVE-2023-4911 https://github.com/Green-Avocado/CVE-2023-4911 https://github.com/xiaoQ1z/CVE-2023-4911 https://github.com/Diego-AltF4/CVE-2023-4911 https://github.com/KernelKrise/CVE-2023-4911 https:/ • CWE-122: Heap-based Buffer Overflow CWE-787: Out-of-bounds Write •

CVE-2023-44488 – libvpx: crash related to VP9 encoding in libvpx
https://notcve.org/view.php?id=CVE-2023-44488
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 • CWE-755: Improper Handling of Exceptional Conditions •
CVE-2023-39194 – Kernel: xfrm: out-of-bounds read in __xfrm_state_filter_match()
https://notcve.org/view.php?id=CVE-2023-39194
A flaw was found in the XFRM subsystem in the Linux kernel. The specific flaw exists within the processing of state filters, which can result in a read past the end of an allocated buffer. This flaw allows a local privileged (CAP_NET_ADMIN) attacker to trigger an out-of-bounds read, potentially leading to an information disclosure. Se encontró una falla en el subsistema XFRM del kernel de Linux. La falla específica existe en el procesamiento de filtros de estado, lo que puede resultar en una lectura más allá del final de un búfer asignado. • https://access.redhat.com/errata/RHSA-2024:2394 https://access.redhat.com/errata/RHSA-2024:2950 https://access.redhat.com/errata/RHSA-2024:3138 https://access.redhat.com/security/cve/CVE-2023-39194 https://bugzilla.redhat.com/show_bug.cgi?id=2226788 https://lists.debian.org/debian-lts-announce/2024/01/msg00004.html https://www.zerodayinitiative.com/advisories/ZDI-CAN-18111 • CWE-125: Out-of-bounds Read •
