Asterisk is an open source telephony engine and toolkit.

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).

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.

There is no known workaround at this time.

All Asterisk users should upgrade to the latest version:


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