"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,
1.8.15.1, 10.7.1, and 10.7.1-digiumphones.

These releases are available for immediate download at
http://downloads.asterisk.org/pub/telephony/asterisk/releases

The release of Asterisk 1.8.11-cert7, 1.8.15.1, 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 peer.

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.
