Test ID:	1.3.6.1.4.1.25623.1.0.64753
Category:	Debian Local Security Checks
Title:	Debian: Security Advisory (DSA-1870-1)
Summary:	The remote host is missing an update for the Debian 'pidgin' package(s) announced via the DSA-1870-1 advisory.
Description:	Summary: The remote host is missing an update for the Debian 'pidgin' package(s) announced via the DSA-1870-1 advisory. Vulnerability Insight: 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 (lenny), this problem has been fixed in version 2.4.3-4lenny3. For the testing distribution (squeeze), this problem will be fixed soon. For the unstable distribution (sid), this problem has been fixed in version 2.5.9-1. We recommend that you upgrade your pidgin packages. Affected Software/OS: 'pidgin' package(s) on Debian 5. Solution: Please install the updated package(s). CVSS Score: 10.0 CVSS Vector: AV:N/AC:L/Au:N/C:C/I:C/A:C
