Test ID:	1.3.6.1.4.1.25623.1.1.10.2022.0010
Category:	Mageia Linux Local Security Checks
Title:	Mageia: Security Advisory (MGASA-2022-0010)
Summary:	The remote host is missing an update for the 'squashfs-tools' package(s) announced via the MGASA-2022-0010 advisory.
Description:	Summary: The remote host is missing an update for the 'squashfs-tools' package(s) announced via the MGASA-2022-0010 advisory. Vulnerability Insight: squashfs_opendir in unsquash-1.c in Squashfs-Tools 4.5 stores the filename in the directory entry, this is then used by unsquashfs to create the new file during the unsquash. The filename is not validated for traversal outside of the destination directory, and thus allows writing to locations outside of the destination. (CVE-2021-40153) squashfs_opendir in unsquash-2.c in Squashfs-Tools 4.5 allows Directory Traversal, a different vulnerability than CVE-2021-40153. A squashfs filesystem that has been crafted to include a symbolic link and then contents under the same filename in a filesystem can cause unsquashfs to first create the symbolic link pointing outside the expected directory, and then the subsequent write operation will cause the unsquashfs process to write through the symbolic link elsewhere in the filesystem. (CVE-2021-41072) Affected Software/OS: 'squashfs-tools' package(s) on Mageia 8. Solution: Please install the updated package(s). CVSS Score: 5.8 CVSS Vector: AV:N/AC:M/Au:N/C:N/I:P/A:P
