    Just Ferguson discovered that libotr, an off-the-record (OTR) messaging
    library, can be forced to perform zero-length allocations for heap buffers
    that are used in base64 decoding routines.  An attacker can exploit this
    flaw by sending crafted messages to an application that is using libotr to
    perform denial of service attacks or potentially execute arbitrary code.
    
    For the stable distribution (squeeze), this problem has been fixed in
    version 3.2.0-2+squeeze1.
    
    For the testing distribution (wheezy), this problem has been fixed in
