Mandriva Linux Security Advisory 2013-140

Posted Apr 11, 2013

Mandriva Linux Security Advisory 2013-140 - 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 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 reading additional text in a 403 observing whether certain retransmissions occur. 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 header. 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. The updated packages have upgraded to the 11.2.2 version which is not vulnerable to these issues

Asterisk Project Security Advisory - AST-2013-002

Posted Mar 28, 2013

Authored by Mark Michelson | Site asterisk.org

Asterisk Project Security Advisory - AST-2012-014, fixed in January of this year, contained a fix for Asterisk's HTTP server since it was susceptible to a remotely-triggered crash. The fix put in place fixed the possibility for the crash to be triggered, but a possible denial of service still exists if an attacker sends one or more HTTP POST requests with very large Content-Length values.
