-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 - ------------------------------------------------------------------------- Debian Security Advisory DSA-2526-1 security@debian.org http://www.debian.org/security/ Nico Golde August 12, 2012 http://www.debian.org/security/faq - ------------------------------------------------------------------------- Package : libotr Vulnerability : heap-based buffer overflows Problem type : remote Debian-specific: no Debian bug : 684121 CVE ID : CVE-2012-3461 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 version 3.2.1-1. For the unstable distribution (sid), this problem has been fixed in version 3.2.1-1. We recommend that you upgrade your libotr packages.
