The Asterisk Development Team has announced security releases for Certified
Asterisk 1.8.28 and 11.6 and Asterisk 1.8, 11, 12, and 13. The available
security releases are released as versions 1.8.28.cert-4, 1.8.32.2, 11.6-cert10,
11.15.1, 12.8.1, and 13.1.1.

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

The release of these versions resolves the following security vulnerabilities:

* AST-2015-001: File descriptor leak when incompatible codecs are offered

Asterisk may be configured to only allow specific audio or
video codecs to be used when communicating with a
particular endpoint. When an endpoint sends an SDP offer
that only lists codecs not allowed by Asterisk, the offer
is rejected. However, in this case, RTP ports that are
allocated in the process are not reclaimed.

This issue only affects the PJSIP channel driver in
Asterisk. Users of the chan_sip channel driver are not
affected.

* AST-2015-002: Mitigation for libcURL HTTP request injection vulnerability

CVE-2014-8150 reported an HTTP request injection
vulnerability in libcURL. Asterisk uses libcURL in its
func_curl.so module (the CURL() dialplan function), as well
as its res_config_curl.so (cURL realtime backend) modules.

Since Asterisk may be configured to allow for user-supplied
URLs to be passed to libcURL, it is possible that an
attacker could use Asterisk as an attack vector to inject
unauthorized HTTP requests if the version of libcURL
installed on the Asterisk server is affected by
CVE-2014-8150.

For more information about the details of these vulnerabilities, please read
security advisory AST-2015-001 and AST-2015-002, which were released at the same
time as this announcement.
