The SIP channel driver in Asterisk Open Source 1.8.x before 1.8.20.2,
10.x before 10.12.2, and 11.x before 11.2.2; Certified Asterisk 1.8.15
before 1.8.15-cert2; Asterisk Business Edition (BE) C.3.x before
C.3.8.1; and Asterisk Digiumphones 10.x-digiumphones before
10.12.2-digiumphones exhibits different behavior for invalid INVITE,
SUBSCRIBE, and REGISTER transactions depending on whether the user
account exists, which allows remote attackers to enumerate account
names by (1) reading HTTP status codes, (2) reading additional text in
a 403 (aka Forbidden) response, or (3) observing whether certain
retransmissions occur (CVE-2013-2264).

Stack-based buffer overflow in res/res_format_attr_h264.c in Asterisk
Open Source 11.x before 11.2.2 allows remote attackers to execute
arbitrary code via a long sprop-parameter-sets H.264 media attribute
in a SIP Session Description Protocol (SDP) header (CVE-2013-2685).

main/http.c in the HTTP server in Asterisk Open Source 1.8.x before
1.8.20.2, 10.x before 10.12.2, and 11.x before 11.2.2; Certified
Asterisk 1.8.15 before 1.8.15-cert2; and Asterisk Digiumphones
10.x-digiumphones before 10.12.2-digiumphones does not properly
restrict Content-Length values, which allows remote attackers to
conduct stack-consumption attacks and cause a denial of service
(daemon crash) via a crafted HTTP POST request. NOTE: this
vulnerability exists because of an incorrect fix for CVE-2012-5976
(CVE-2013-2686).

The updated packages have upgraded to the 11.2.2 version which is not
vulnerable to these issues"

"The Asterisk Development Team has announced security releases for
Certified Asterisk 1.8.15 and Asterisk 1.8, 10, and 11. The available
security releases are released as versions 1.8.15-cert2, 1.8.20.2,
10.12.2, 10.12.2-digiumphones, and 11.2.2.

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

The release of these versions resolve the following issues :

  - A possible buffer overflow during H.264 format
    negotiation. The format attribute resource for H.264
    video performs an unsafe read against a media attribute
    when parsing the SDP.

    This vulnerability only affected Asterisk 11.

  - A denial of service exists in Asterisk's HTTP server.
    AST-2012-014, fixed in January of this year, contained a
    fix for Asterisk's HTTP server for a remotely-triggered
    crash. While the fix prevented the crash from being
    triggered, a denial of service vector still exists with
    that solution if an attacker sends one or more HTTP POST
    requests with very large Content-Length values.

    This vulnerability affects Certified Asterisk 1.8.15,
    Asterisk 1.8, 10, and 11

  - A potential username disclosure exists in the SIP
    channel driver. When authenticating a SIP request with
    alwaysauthreject enabled, allowguest disabled, and
    autocreatepeer disabled, Asterisk discloses whether a
    user exists for INVITE, SUBSCRIBE, and REGISTER
    transactions in multiple ways.

    This vulnerability affects Certified Asterisk 1.8.15,
    Asterisk 1.8, 10, and 11

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-2013-001, AST-2013-002, and
AST-2013-003, which were released at the same time as this
announcement.
