Summary     : The Open Source PBX
Description :
Asterisk is a complete PBX in software. It runs on Linux and provides
all of the features you would expect from a PBX and more. Asterisk
does voice over IP in three protocols, and can interoperate with
almost all standards-based telephony equipment using relatively
inexpensive hardware.

Update Information:

fix build on s390
The Asterisk Development Team has announced security releases for Certified
Asterisk 1.8.11 and Asterisk 1.8 and 10. The available security releases are
released as versions 1.8.11-cert7,, 10.7.1, and 10.7.1-digiumphones.

These releases are available for immediate download at

The release of Asterisk 1.8.11-cert7,, 10.7.1, and 10.7.1-digiumphones
resolve the following two issues:

* A permission escalation vulnerability in Asterisk Manager Interface.  This
  would potentially allow remote authenticated users the ability to execute
  commands on the system shell with the privileges of the user running the
  Asterisk application.  Please note that the README-SERIOUSLY.bestpractices.txt
  file delivered with Asterisk has been updated due to this and other related
  vulnerabilities fixed in previous versions of Asterisk.

* When an IAX2 call is made using the credentials of a peer defined in a
  dynamic Asterisk Realtime Architecture (ARA) backend, the ACL rules for that
  peer are not applied to the call attempt. This allows for a remote attacker
  who is aware of a peer's credentials to bypass the ACL rules set for that

These issues and their resolutions are described in the security advisories.

For more information about the details of these vulnerabilities, please read
security advisories AST-2012-012 and AST-2012-013, which were released at the
same time as this announcement.
