GNU ZRTPCPP before 3.2.0 allows remote attackers to obtain sensitive information (uninitialized heap memory) or cause a denial of service (out-of-bounds read) via a crafted packet, as demonstrated by a truncated Ping packet that is not properly handled by the getEpHash function.
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.
