high Nessus Plugin ID 141066

Language:

Synopsis

The remote Gentoo host is missing one or more security-related patches.

Description

The remote host is affected by the vulnerability described in GLSA-202009-16 (LinuxCIFS: Shell injection)

 The mount.cifs utility had a shell injection issue where one can embed shell commands via the username mount option. Those commands will be run via popen() in the context of the user calling mount.
 Impact :

 A remote attacker could entice a user to use a specially crafted argument using mount.cifs, possibly resulting in execution of arbitrary code with the privileges of the process or a Denial of Service condition.
 Workaround :

 There is no known workaround at this time.

Solution

All LinuxCIFS users should upgrade to the latest version:
 # emerge --sync # emerge --ask --oneshot --verbose '>=net-fs/cifs-utils-6.11'
