[ MDVSA-2010:041 ] pidgin

[dude67]

_______________________________________________________________________

Package : pidgin
Date : February 18, 2010
Affected: 2008.0, 2009.1, 2010.0, Enterprise Server 5.0
_______________________________________________________________________

Problem Description:

Multiple security vulnerabilities has been identified and fixed
in pidgin:

Certain malformed SLP messages can trigger a crash because the MSN
protocol plugin fails to check that all pieces of the message are
set correctly (CVE-2010-0277).

In a user in a multi-user chat room has a nickname containing '<br>'
then libpurple ends up having two users with username ' ' in the room,
and Finch crashes in this situation. We do not believe there is a
possibility of remote code execution (CVE-2010-0420).

oCERT notified us about a problem in Pidgin, where a large amount of
processing time will be used when inserting many smileys into an IM
or chat window. This should not cause a crash, but Pidgin can become
unusable slow (CVE-2010-0423).

Packages for 2008.0 are provided for Corporate Desktop 2008.0
customers.

This update provides pidgin 2.6.6, which is not vulnerable to these
issues.
