Problem description

A vulnerability was found and corrected in libotr:

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 (CVE-2012-3461).

The updated packages have been patched to correct this issue.
