CVSS: 7.5EPSS: 0%CPEs: 24EXPL: 0CVE-2022-27649 – podman: Default inheritable capabilities for linux container should be empty
https://notcve.org/view.php?id=CVE-2022-27649
A flaw was found in Podman, where containers were started incorrectly with non-empty default permissions. A vulnerability was found in Moby (Docker Engine), where containers were started incorrectly with non-empty inheritable Linux process capabilities. This flaw allows an attacker with access to programs with inheritable file capabilities to elevate those capabilities to the permitted set when execve(2) runs. Se ha encontrado un fallo en Podman, donde los contenedores eran iniciados incorrectamente con permisos por defecto no vacíos. Se ha encontrado una vulnerabilidad en Moby (Docker Engine), donde los contenedores eran iniciados incorrectamente con capacidades de proceso Linux heredables no vacías. • https://bugzilla.redhat.com/show_bug.cgi?id=2066568 https://github.com/containers/podman/commit/aafa80918a245edcbdaceb1191d749570f1872d0 https://github.com/containers/podman/security/advisories/GHSA-qvf8-p83w-v58j https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/4KDETHL5XCT6RZN2BBNOCEXRZ2W3SFU3 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/DLUJZV3HBP56ADXU6QH2V7RNYUPMVBXQ https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org&#x • CWE-276: Incorrect Default Permissions •

https://notcve.org/view.php?id=CVE-2022-1011
A use-after-free flaw was found in the Linux kernel’s FUSE filesystem in the way a user triggers write(). This flaw allows a local user to gain unauthorized access to data from the FUSE filesystem, resulting in privilege escalation.

https://notcve.org/view.php?id=CVE-2021-31566
An improper link resolution flaw can occur while extracting an archive leading to changing modes, times, access control lists, and flags of a file outside of the archive. An attacker may provide a malicious archive to a victim user, who would trigger this flaw when trying to extract the archive. A local attacker may use this flaw to gain more privileges in a system. Un fallo de resolución de enlaces inapropiado puede ocurrir mientras es extraído un archivo que conlleva a un cambio de modos, tiempos, listas de control de acceso y flags de un archivo fuera del archivo.
