Detail

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 12.04 LTS - Ubuntu 11.10 - Ubuntu 11.04 - Ubuntu 10.04 LTS

Summary:

Applications using Off-the-Record messaging plugins could be made to crash or run programs if it received specially crafted network messages.

Software Description: - libotr: Off-the-Record Messaging library

Details:

Justin Ferguson discovered multiple heap overflows in libotr. A remote attacker could use this to craft a malformed OTR message that could cause a denial of service via application crash or possibly execute arbitrary code.

Update instructions:

The problem can be corrected by updating your system to the following package versions:

Ubuntu 12.04 LTS:
libotr2 3.2.0-4ubuntu0.1

Ubuntu 11.10:
libotr2 3.2.0-2.1ubuntu0.1

Ubuntu 11.04:
libotr2 3.2.0-2ubuntu1.1

Ubuntu 10.04 LTS:
libotr2 3.2.0-2ubuntu0.1

After a standard system update you need to restart any instant messaging applications using an Off-the-Record messaging plugin to make all the necessary changes.

Title: DSA-2526-1 libotr - buffer overflow
Description: 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.
