applications using the Libevent evbuffer API. This defect leaves
applications which pass insanely large inputs to evbuffers open to a
possible heap overflow or infinite loop. In order to exploit this
flaw, an attacker needs to be able to find a way to provoke the
program into trying to make a buffer chunk larger than what will fit
into a single size_t or off_t."
