Synopsis
========

A vulnerability in LinuxCIFS utils' "cifscreds" PAM module might
allow
remote attackers to have an unspecified impact via unknown vectors.

Background
==========

The LinuxCIFS utils are a collection of tools for managing Linux CIFS
Client Filesystems.

Affected packages
=================

-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 net-fs/cifs-utils < 6.4 >= 6.4

Description
===========

A stack-based buffer overflow was discovered in cifskey.c or
cifscreds.c in LinuxCIFS, as used in "pam_cifscreds."

Impact
======

A remote attacker could exploit this vulnerability to cause an
unspecified impact.

Workaround
==========

Don't use LinuxCIFS utils' "cifscreds" PAM module. In Gentoo,
LinuxCIFS
utils' PAM support is disabled by default unless the "pam" USE flag
is
enabled.

Resolution
==========

All LinuxCIFS utils users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose ">=net-fs/cifs-utils-6.4"

References
==========
