libevent: Libevent: Memory corruption due to use-after-free

A flaw was found in Libevent, an event notification library. A use-after-free vulnerability exists in the evbufferaddbufferreference function when it processes an output buffer with a zero length. This can lead to a dangling pointer, which an attacker could exploit to cause memory corruption or...
