Synopsis
========
Multiple vulnerabilities have been discovered in LinuxCIFS utils, the
worst of which can lead to local root privilege escalation.
Background
==========
The LinuxCIFS utils are a collection of tools for managing Linux CIFS
Client Filesystems.
Affected packages
=================
Package Vulnerable Unaffected
----------------- ------------ ------------
net-fs/cifs-utils < 6.15 >= 6.15
Description
===========
Multiple vulnerabilities have been discovered in LinuxCIFS utils. Please
review the CVE identifiers referenced below for details.
Impact
======
A stack-based buffer overflow when parsing the mount.cifs ip= command-
line argument could lead to local attackers gaining root privileges.
When verbose logging is enabled, invalid credentials file lines may be
dumped to stderr. This may lead to information disclosure in particular
conditions when the credentials file given is sensitive and contains '='
signs.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All LinuxCIFS utils users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=net-fs/cifs-utils-6.15"
