Synopsis
========

Multiple vulnerabilities have been found in Linux-PAM, allowing local
attackers to possibly gain escalated privileges, cause a Denial of
Service, corrupt data, or obtain sensitive information.

Background
==========

Linux-PAM (Pluggable Authentication Modules) is an architecture
allowing the separation of the development of privilege granting
software from the development of secure and appropriate authentication
schemes.

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

-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 sys-libs/pam < 1.1.5 >= 1.1.5

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

Multiple vulnerabilities have been discovered in Linux-PAM. Please
review the CVE identifiers referenced below for details.

Impact
======

A local attacker could use specially crafted files to cause a buffer
overflow, possibly resulting in privilege escalation or Denial of
Service. Furthermore, a local attacker could execute specially crafted
programs or symlink attacks, possibly resulting in data loss or
disclosure of sensitive information.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All Linux-PAM users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose ">=sys-libs/pam-1.1.5"

NOTE: This is a legacy GLSA. Updates for all affected architectures are
available since November 25, 2011. It is likely that your system is
already no longer affected by this issue.
