TITLE:
AOL AIM SIPFoundry sipXtapi Buffer Overflow Vulnerabilities
SECUNIA ADVISORY ID:
SA37143
VERIFY ADVISORY:
http://secunia.com/advisories/37143/
DESCRIPTION:
Two vulnerabilities have been reported in AOL AIM, which can be
exploited by malicious people to compromise a user's system.
1) A signedness error in the SIP protocol implementation library
(sipXtapi.dll) when parsing RTCP sender report packets can be
exploited to cause a heap-based buffer overflow.
Successful exploitation may allow execution of arbitrary code, but
requires that a user is tricked into accepting a Video Messaging
session.
2) An error in sipXtapi.dll when parsing RTP information can be
exploited to cause a heap-based buffer overflow via a specially
crafted "Extension Length" RTP header value.
Successful exploitation may allow execution of arbitrary code, but
requires that a user has an active voice session.
SOLUTION:
Update to version 6.8.7.7 or later.
PROVIDED AND/OR DISCOVERED BY:
Reported by wushi of team509 via ZDI.
