EulerOS 2.0 SP9 : squashfs-tools (EulerOS-SA-2022-1039)

high Nessus Plugin ID 157201

Synopsis

The remote EulerOS host is missing a security update.

Description

According to the versions of the squashfs-tools package installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

 - 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)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected squashfs-tools packages.
