Detail

chan_iax2.c in the IAX2 channel driver in Asterisk Open Source 1.4.x before 1.4.41.1, 1.6.2.x before 1.6.2.18.1, and 1.8.x before 1.8.4.3, and Asterisk Business Edition C.3 before C.3.7.3, accesses a memory address contained in an option control frame, which allows remote attackers to cause a denial of service (daemon crash) or possibly have unspecified other impact via a crafted frame.

Title: DSA-2276-1 asterisk -- multiple denial of service
Description: Paul Belanger reported a vulnerability in Asterisk identified as AST-2011-008 through which an unauthenticated attacker may crash an Asterisk server remotely. A package containing a null char causes the SIP header parser to alter unrelated memory structures. Jared Mauch reported a vulnerability in Asterisk identified as AST-2011-009 through which an unauthenticated attacker may crash an Asterisk server remotely. If a user sends a package with a Contact header with a missing left angle bracket the server will crash. A possible workaround is to disable chan_sip. The vulnerability identified as AST-2011-010 reported about an input validation error in the IAX2 channel driver. An unauthenticated attacker may crash an Asterisk server remotely by sending a crafted option control frame.
