CVE-2013-2222 libzrtpcpp: Multiple stack-based buffer overflows when processing certain ZRTP Hello packets
Last modified: 2016-03-04 06:54:37 EST
Multiple stack-based buffer overflows were found in the way libzrtpcpp, a ZRTP support library for the GNU ccRTP stack, processed certain ZRTP Hello packets (ZRTP Hello packets with an overly-large value in certain fields, including the count of public keys). A remote attacker could provide a specially-crafted ZRTP packet that, when processed in an application linked against libzrtpcpp would lead to that application crash.
