util-linux is a random collection of Linux utilities. Before util-linux 2.41.4, parse_dos_extended() in libblkid/src/partitions/dos.c computes an extended-partition start sector with 32-bit addition and does not apply the extended-area bounds checks to the first two EBR entries....
util-linux is a random collection of Linux utilities. In util-linux 2.39.1 through 2.41.4 and 2.42 through 2.42.1, the SUID mount utility reads the attacker-controlled LIBMOUNT_FORCE_MOUNT2 environment variable with getenv(), allowing a local low-privileged user to force the non-...
util-linux is a random collection of Linux utilities. In util-linux 2.17 through 2.41.6 and 2.42 through 2.42.3, and in 2.42.4 when the legacy mount(2) path is used without /proc, restricted non-root mount requests validate an /etc/fstab target before the mount operation re-resol...
util-linux is a random collection of Linux utilities. In util-linux 2.39 through 2.41.4 and 2.42 through 2.42.1, the SUID mount utility's hook_owner.c post-mount hook performs path-based chmod() and lchown() operations on a previously validated mount target. A local low-privilege...
util-linux versions through 2.41.5 and 2.42.2 fail to check mount helper exit status before running post-mount hooks, allowing unprivileged users to execute privileged operations on pre-existing filesystems. Attackers can exploit X-mount.idmap or X-mount.owner hooks to clone file...
util-linux is a random collection of Linux utilities. Prior to version 2.41.4, a TOCTOU (Time-of-Check-Time-of-Use) vulnerability has been identified in the SUID binary /usr/bin/mount from util-linux. The mount binary, when setting up loop devices, validates the source file path...
A flaw was found in util-linux. This vulnerability allows a heap buffer overread when processing 256-byte usernames, specifically within the setpwnam() function, affecting SUID (Set User ID) login-utils utilities writing to the password database.
