Detail

Synopsis

A buffer overflow vulnerability in libotr could allow a remote attacker to execute arbitrary code or cause a Denial of Service condition.

Background

libotr is a portable off-the-record messaging library.

Description

Multiple heap-based buffer overflows are present in the Base64 decoder of libotr.

Impact

A remote attacker could send a specially crafted OTR message, resulting in arbitrary code execution with the privileges of the process or a Denial of Service condition.

Workaround

There is no known workaround at this time.

Resolution

All libotr users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=net-libs/libotr-3.2.1"

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.
