Date:	11/24/2023
Bugs:	#842234
ID:	202311-05

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	Architecture(s)
net-fs/cifs-utils	< 6.15	>= 6.15	All supported architectures

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"
