Synopsis
=======
Multiple vulnerabilities have been found in Asterisk, the worst of
which may allow execution of arbitrary code.

Background
=========
Asterisk is an open source telephony engine and toolkit.

Affected packages
================
    -------------------------------------------------------------------
     Package              /     Vulnerable     /            Unaffected
    -------------------------------------------------------------------
  1  net-misc/asterisk           < 1.8.15.1               >= 1.8.15.1

Description
==========
Multiple vulnerabilities have been found in Asterisk:

* An error in manager.c allows shell access (CVE-2012-2186).
* An error in Asterisk could cause all RTP ports to be exhausted
  (CVE-2012-3812).
* A double-free error could occur when two parties attempt to
  manipulate the same voicemail account simultaneously (CVE-2012-3863).
* Asterisk does not properly implement certain ACL rules
  (CVE-2012-4737).

Impact
=====
A remote, authenticated attacker could execute arbitrary code with the
privileges of the process, cause a Denial of Service condition, or
bypass outbound call restrictions.

Workaround
=========
There is no known workaround at this time.

Resolution
=========
All Asterisk users should upgrade to the latest version:

  # emerge --sync
  # emerge --ask --oneshot --verbose ">=net-misc/asterisk-1.8.15.1"
