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.
For the stable distribution (wheezy), this problem has been fixed in version 2.0.19-stable-3+deb7u1.
For the upcoming stable distribution (jessie) and the unstable distribution (sid), this problem will be fixed soon.
We recommend that you upgrade your libevent packages.");
