Synopsis
========

Multiple vulnerabilities have been found in OpenAFS, worst of which can
allow attackers to execute arbitrary code

Background
==========

OpenAFS is an client-server program suite for federated file sharing
and replicated content distribution.

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

    -------------------------------------------------------------------
     Package              /     Vulnerable     /            Unaffected
    -------------------------------------------------------------------
  1  net-fs/openafs               < 1.6.5                    >= 1.6.5 

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

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

Impact
======

An attacker could potentially execute arbitrary code with the
permissions of the user running the AFS server, cause a Denial of
Service condition, or gain access to sensitive information.
Additionally, an attacker could compromise a cell's private key,
allowing them to impersonate any user in the cell.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All OpenAFS users should upgrade to the latest version:

  # emerge --sync
  # emerge --ask --oneshot --verbose ">=net-fs/openafs-1.6.5"
