-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 _______________________________________________________________________ Mandriva Linux Security Advisory MDVSA-2012:131 http://www.mandriva.com/security/ _______________________________________________________________________ Package : libotr Date : August 13, 2012 Affected: 2011. _______________________________________________________________________ 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. _______________________________________________________________________ References: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2012-3461 _______________________________________________________________________ Updated Packages: Mandriva Linux 2011: 7248af52fb3ea459d0c7e65907631bda 2011/i586/libotr2-3.2.0-5.1-mdv2011.0.i586.rpm 9e3d6867954096a67cdd69df3c688b91 2011/i586/libotr-devel-3.2.0-5.1-mdv2011.0.i586.rpm d0fdea9fc83385a6540881a99b70e06f 2011/i586/libotr-utils-3.2.0-5.1-mdv2011.0.i586.rpm c2cca963b8a3ed1c48a9913251088a57 2011/SRPMS/libotr-3.2.0-5.1.src.rpm Mandriva Linux 2011/X86_64: 4ba040455e37c5ff708f1b653a50a980 2011/x86_64/lib64otr2-3.2.0-5.1-mdv2011.0.x86_64.rpm 34d39b44c8a2774cb4d17685ad128697 2011/x86_64/lib64otr-devel-3.2.0-5.1-mdv2011.0.x86_64.rpm c394a5107bc015193c97a3d9cc092f4e 2011/x86_64/libotr-utils-3.2.0-5.1-mdv2011.0.x86_64.rpm c2cca963b8a3ed1c48a9913251088a57 2011/SRPMS/libotr-3.2.0-5.1.src.rpm _______________________________________________________________________ To upgrade automatically use MandrivaUpdate or urpmi.
