16 Apr 2021 — Shiftfs, an out-of-tree stacking file system included in Ubuntu Linux kernels, did not properly handle faults occurring during copy_from_user() correctly. These could lead to either a double-free situation or memory not being freed at all. An attacker could use this to cause a denial of service (kernel memory exhaustion) or gain privileges via executing arbitrary code. AKA ZDI-CAN-13562. Shiftfs, un sistema de archivos de apilamiento fuera del árbol incluido en los kernels de Ubuntu Linux, no manejaba aprop... • https://github.com/synacktiv/CVE-2021-3492 • CWE-401: Missing Release of Memory after Effective Lifetime CWE-415: Double Free •

16 Apr 2021 — The overlayfs implementation in the linux kernel did not properly validate with respect to user namespaces the setting of file capabilities on files in an underlying file system. Due to the combination of unprivileged user namespaces along with a patch carried in the Ubuntu kernel to allow unprivileged overlay mounts, an attacker could use this to gain elevated privileges. La implementación de overlayfs en el kernel de Linux no comprobó apropiadamente con respecto a los espacios de nombre de los usuarios, l... • https://packetstorm.news/files/id/162866 • CWE-270: Privilege Context Switching Error CWE-863: Incorrect Authorization •

15 Dec 2016 — An issue was discovered in Apport before 2.20.4. In apport/ui.py, Apport reads the CrashDB field and it then evaluates the field as Python code if it begins with a "{". This allows remote attackers to execute arbitrary Python code. Un problema fue descubierto en Apport en versiones anteriores a 2.20.4. En apport/ui.py, Apport lee el campo CashDB y después evalúa el campo como código Python si comienza con un "{". • https://packetstorm.news/files/id/140207 • CWE-94: Improper Control of Generation of Code ('Code Injection') •

15 Dec 2016 — An issue was discovered in Apport before 2.20.4. There is a path traversal issue in the Apport crash file "Package" and "SourcePackage" fields. These fields are used to build a path to the package specific hook files in the /usr/share/apport/package-hooks/ directory. An attacker can exploit this path traversal to execute arbitrary Python files from the local system. Un problema fue descubierto en Apport en versiones anteriores a 2.20.4. • https://packetstorm.news/files/id/140207 • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') •

15 Jun 2015 — The overlayfs implementation in the linux (aka Linux kernel) package before 3.19.0-21.21 in Ubuntu through 15.04 does not properly check permissions for file creation in the upper filesystem directory, which allows local users to obtain root access by leveraging a configuration in which overlayfs is permitted in an arbitrary mount namespace.

21 Sep 2009 — The postfix.postinst script in the Debian GNU/Linux and Ubuntu postfix 2.5.5 package grants the postfix user write access to /var/spool/postfix/pid, which might allow local users to conduct symlink attacks that overwrite arbitrary files. El script postfix.postinst en el paquete postfix v2.5.5 de Debian GNU/Linux y Ubuntu permite acceso de escritura al usuario postfix en /var/spool/postfix/pid, permitiendo a usuarios locales dirigir ataques de enlaces simbólicos que sobrescriban ficheros de su elección. • http://www.debian.org/security/2011/dsa-2233 • CWE-59: Improper Link Resolution Before File Access ('Link Following') •
