 Package : pidgin
 Date    : April 28, 2010
 Affected: 2009.0
 _______________________________________________________________________

 Problem 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
 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).
 
 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.
