DSA-1870-1 pidgin -- insufficient input validation

ID: oval:org.secpod.oval:def:600268Date: (C)2011-05-13   (M)2017-10-04
Class: PATCHFamily: unix




Federico Muttis discovered that libpurple, the shared library that adds support for various instant messaging networks to the pidgin IM client, is vulnerable to a heap-based buffer overflow. This issue exists because of an incomplete fix for CVE-2008-2927 and CVE-2009-1376. An attacker can exploit this by sending two consecutive SLP packets to a victim via MSN. The first packet is used to create an SLP message object with an offset of zero, the second packet then contains a crafted offset which hits the vulnerable code originally fixed in CVE-2008-2927 and CVE-2009-1376 and allows an attacker to execute arbitrary code. Note: Users with the "Allow only the users below" setting are not vulnerable to this attack. If you can"t install the below updates you may want to set this via Tools->Privacy. For the stable distribution , this problem has been fixed in version 2.4.3-4lenny3. For the testing distribution , this problem will be fixed soon. For the unstable distribution , this problem has been fixed in version 2.5.9-1. We recommend that you upgrade your pidgin packages.
