Debian DLA-853-1 : pidgin security update

critical Nessus Plugin ID 97669

Language:

Synopsis

The remote Debian host is missing a security update.

Description

It was discovered that an invalid XML file can trigger an out-of-bound memory access in Pidgin, a multi-protocol instant messaging client, when it is sent by a malicious server. This might lead to a crash or, in some extreme cases, to remote code execution in the client-side.

For Debian 7 'Wheezy', these problems have been fixed in version 2.10.10-1~deb7u3.

We recommend that you upgrade your pidgin packages.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Upgrade the affected packages.
