Andrew Bartlett of Catalyst reported a defect affecting certain 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 (CVE-2014-6272).");
