    Debian Bug     : 774645
    
    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.
    
    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.
