openSUSE 15 Security Update : firejail (openSUSE-SU-2022:10015-1)

high Nessus Plugin ID 162481

Language:

Synopsis

The remote SUSE host is missing a security update.

Description

The remote SUSE Linux SUSE15 host has a package installed that is affected by a vulnerability as referenced in the openSUSE-SU-2022:10015-1 advisory.

 - A Privilege Context Switching issue was discovered in join.c in Firejail 0.9.68. By crafting a bogus Firejail container that is accepted by the Firejail setuid-root program as a join target, a local attacker can enter an environment in which the Linux user namespace is still the initial user namespace, the NO_NEW_PRIVS prctl is not activated, and the entered mount namespace is under the attacker's control. In this way, the filesystem layout can be adjusted to gain root privileges through execution of available setuid-root binaries such as su or sudo. (CVE-2022-31214)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected firejail package.
