Heap-based buffer overflow in the ZRtp::storeMsgTemp function in GNU ZRTPCPP before 3.2.0 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a large packet.
The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.
