https://notcve.org/view.php?id=CVE-2021-45417
AIDE before 0.17.4 allows local users to obtain root privileges via crafted file metadata (such as XFS extended attributes or tmpfs ACLs), because of a heap-based buffer overflow. AIDE versiones anteriores a 0.17.4, permite a usuarios locales obtener privilegios de root por medio de metadatos de archivo diseñados (como atributos extendidos de XFS o ACLs de tmpfs), debido a un desbordamiento de búfer en la región heap de la memoria A heap-based buffer overflow vulnerability in the base64 functions of AIDE, an advanced intrusion detection system.

https://notcve.org/view.php?id=CVE-2022-20698
A vulnerability in the OOXML parsing module in Clam AntiVirus (ClamAV) Software version 0.104.1 and LTS version 0.103.4 and prior versions could allow an unauthenticated, remote attacker to cause a denial of service condition on an affected device. The vulnerability is due to improper checks that may result in an invalid pointer read. An attacker could exploit this vulnerability by sending a crafted OOXML file to an affected device. An exploit could allow the attacker to cause the ClamAV scanning process to crash, resulting in a denial of service condition. Una vulnerabilidad en el módulo de análisis de OOXML en el software Clam AntiVirus (ClamAV) versión 0.104.1 y LTS versiones 0.103.4 y anteriores, podría permitir a un atacante remoto no autenticado causar una condición de denegación de servicio en un dispositivo afectado. • https://blog.clamav.net/2022/01/clamav-01035-and-01042-security-patch.html https://security.gentoo.org/glsa/202310-01 • CWE-20: Improper Input Validation CWE-125: Out-of-bounds Read •

https://notcve.org/view.php?id=CVE-2021-3939
Ubuntu-specific modifications to accountsservice (in patch file debian/patches/0010-set-language.patch) caused the fallback_locale variable, pointing to static storage, to be freed, in the user_change_language_authorized_cb function. This is reachable via the SetLanguage dbus function. This is fixed in versions 0.6.55-0ubuntu12~20.04.5, 0.6.55-0ubuntu13.3, 0.6.55-0ubuntu14.1. Unas modificaciones específicas de Ubuntu a accountsservice (en el archivo de parche debian/patches/0010-set-language.patch) causaron la liberación de la variable fallback_locale, que apunta al almacenamiento estático, en la función user_change_language_authorized_cb. Esto es accesible por medio de la función dbus SetLanguage. • http://packetstormsecurity.com/files/172848/Ubuntu-accountsservice-Double-Free-Memory-Corruption.html https://bugs.launchpad.net/ubuntu/+source/accountsservice/+bug/1950149 https://ubuntu.com/security/notices/USN-5149-1 • CWE-590: Free of Memory not on the Heap CWE-763: Release of Invalid Pointer or Reference •
