Description Jan Lieskovsky 2013-07-03 13:17:42 UTC

Multiple information (heap memory content) exposure flaws were found in the way libzrtpcpp, a ZRTP support library for the GNU ccRTP stack, processed truncated ZRTP Ping packets. A remote attacker could provide a specially-crafted ZRTP Ping packet that, when processed in an application linked against libzrtpcpp would potentially reveal sensitive information stored on the heap.
