CVSS: 7.8EPSS: 3%CPEs: 18EXPL: 18CVE-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 •
CVSS: 7.8EPSS: 0%CPEs: 7EXPL: 0CVE-2023-5345 – Use-after-free in Linux kernel's fs/smb/client component
https://notcve.org/view.php?id=CVE-2023-5345
A use-after-free vulnerability in the Linux kernel's fs/smb/client component can be exploited to achieve local privilege escalation. In case of an error in smb3_fs_context_parse_param, ctx->password was freed but the field was not set to NULL which could lead to double free. We recommend upgrading past commit e6e43b8aa7cd3c3af686caf0c2e11819a886d705. Se puede explotar una vulnerabilidad de use-after-free en el componente fs/smb/client del kernel de Linux para lograr una escalada de privilegios local. En caso de un error en smb3_fs_context_parse_param, se liberó ctx->password pero el campo no se configuró en NULL, lo que podría provocar una doble liberación. Recomendamos actualizar al commit anterior e6e43b8aa7cd3c3af686caf0c2e11819a886d705. A flaw was found in the SMB client component in the Linux kernel. • http://packetstormsecurity.com/files/177029/Kernel-Live-Patch-Security-Notice-LSN-0100-1.html https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=e6e43b8aa7cd3c3af686caf0c2e11819a886d705 https://kernel.dance/e6e43b8aa7cd3c3af686caf0c2e11819a886d705 https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/GISYSL3F6WIEVGHJGLC2MFNTUXHPTKQH https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/GPMICQ2HVZO5UAM5KPXHAZKA2U3ZDOO6 https://lists.fedoraproject.org&#x • CWE-416: Use After Free •

CVSS: 8.8EPSS: 1%CPEs: 5EXPL: 0CVE-2023-43655 – Remote Code Execution via web-accessible composer.phar
https://notcve.org/view.php?id=CVE-2023-43655
Composer is a dependency manager for PHP. Users publishing a composer.phar to a public web-accessible server where the composer.phar can be executed as a php file may be subject to a remote code execution vulnerability if PHP also has `register_argc_argv` enabled in php.ini. Versions 2.6.4, 2.2.22 and 1.10.27 patch this vulnerability. Users are advised to upgrade. Users unable to upgrade should make sure `register_argc_argv` is disabled in php.ini, and avoid publishing composer.phar to the web as this is not best practice. • https://github.com/composer/composer/commit/4fce14795aba98e40b6c4f5047305aba17a6120d https://github.com/composer/composer/commit/955a48e6319c8962e5cd421b07c00ab3c728968c https://github.com/composer/composer/commit/95e091c921037b7b6564942845e7b738f6b95c9c https://github.com/composer/composer/security/advisories/GHSA-jm6m-4632-36hf https://lists.debian.org/debian-lts-announce/2024/03/msg00030.html https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/66H2WKFUO255T3BZTL72TNYJYH2XM5FG https://lists.fedoraproject.org/arch • CWE-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection') •

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 •
