Mandriva Linux Security Advisory : pidgin (MDVSA-2010:085)

This script is Copyright (C) 2010-2016 Tenable Network Security, Inc.


Synopsis :

The remote Mandriva Linux host is missing one or more security
updates.

Description :

Security vulnerabilities has been identified and fixed in pidgin :

The OSCAR protocol plugin in libpurple in Pidgin before 2.6.3 and
Adium before 1.3.7 allows remote attackers to cause a denial of
service (application crash) via crafted contact-list data for (1) ICQ
and possibly (2) AIM, as demonstrated by the SIM IM client
(CVE-2009-3615).

Directory traversal vulnerability in slp.c in the MSN protocol plugin
in libpurple in Pidgin 2.6.4 and Adium 1.3.8 allows remote attackers
to read arbitrary files via a .. (dot dot) in an
application/x-msnmsgrp2p MSN emoticon (aka custom smiley) request, a
related issue to CVE-2004-0122. NOTE: it could be argued that this is
resultant from a vulnerability in which an emoticon download request
is processed even without a preceding text/x-mms-emoticon message that
announced availability of the emoticon (CVE-2010-0013).

Directory traversal vulnerability in slp.c in the MSN protocol plugin
in libpurple in Pidgin 2.6.4 and Adium 1.3.8 allows remote attackers
to read arbitrary files via a .. (dot dot) in an

related issue to CVE-2004-0122. NOTE: it could be argued that this is
resultant from a vulnerability in which an emoticon download request
is processed even without a preceding text/x-mms-emoticon message that
announced availability of the emoticon (CVE-2010-0013).

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 2009.0 are provided due to the Extended Maintenance
Program.

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