Mandriva Linux Security Advisory : libotr (MDVSA-2012:131)

Medium Nessus Plugin ID 61980


The remote Mandriva Linux host is missing one or more security updates.


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.


Update the affected packages.
