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
==========
