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 •
