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

A security vulnerability has been identified and fixed in pidgin :

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).

This update provides pidgin 2.6.5, which is not vulnerable to this issue.

2.6.6 with security and numerous minor bug fixes CVE-2010-0277 CVE-2010-0420 CVE-2010-0423

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).

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.

The remote host is affected by the vulnerability described in GLSA-201206-11 (Pidgin: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in Pidgin. Please review       the CVE identifiers referenced below for details.
  Impact :

    These vulnerabilities allow for arbitrary file retrieval, Denial of       Service and arbitrary code execution with the privileges of the user       running Pidgin.
  Workaround :

    There is no known workaround at this time.

The version of Pidgin installed on the remote host is earlier than 2.6.5.  Such versions have a directory traversal vulnerability when processing an MSN emoticon request.  A remote attacker could exploit this to read arbitrary files.

It was discovered that Pidgin did not properly handle certain topic messages in the IRC protocol handler. If a user were tricked into connecting to a malicious IRC server, an attacker could cause Pidgin to crash, leading to a denial of service. This issue only affected Ubuntu 8.04 LTS, Ubuntu 8.10 and Ubuntu 9.04. (CVE-2009-2703)

It was discovered that Pidgin did not properly enforce the 'require TLS/SSL' setting when connecting to certain older Jabber servers. If a remote attacker were able to perform a man-in-the-middle attack, this flaw could be exploited to view sensitive information. This issue only affected Ubuntu 8.04 LTS, Ubuntu 8.10 and Ubuntu 9.04. (CVE-2009-3026)

It was discovered that Pidgin did not properly handle certain SLP invite messages in the MSN protocol handler. A remote attacker could send a specially crafted invite message and cause Pidgin to crash, leading to a denial of service. This issue only affected Ubuntu 8.04 LTS, Ubuntu 8.10 and Ubuntu 9.04. (CVE-2009-3083)

It was discovered that Pidgin did not properly handle certain errors in the XMPP protocol handler. A remote attacker could send a specially crafted message and cause Pidgin to crash, leading to a denial of service. This issue only affected Ubuntu 8.10 and Ubuntu 9.04.
(CVE-2009-3085)

It was discovered that Pidgin did not properly handle malformed contact-list data in the OSCAR protocol handler. A remote attacker could send specially crafted contact-list data and cause Pidgin to crash, leading to a denial of service. (CVE-2009-3615)

It was discovered that Pidgin did not properly handle custom smiley requests in the MSN protocol handler. A remote attacker could send a specially crafted filename in a custom smiley request and obtain arbitrary files via directory traversal. This issue only affected Ubuntu 8.10, Ubuntu 9.04 and Ubuntu 9.10. (CVE-2010-0013)

Pidgin for Ubuntu 8.04 LTS was also updated to fix connection issues with the MSN protocol.

USN-675-1 and USN-781-1 provided updated Pidgin packages to fix multiple security vulnerabilities in Ubuntu 8.04 LTS. The security patches to fix CVE-2008-2955 and CVE-2009-1376 were incomplete. This update corrects the problem. 

It was discovered that Pidgin did not properly handle file transfers containing a long filename and special characters in the MSN protocol handler. A remote attacker could send a specially crafted filename in a file transfer request and cause Pidgin to crash, leading to a denial of service. (CVE-2008-2955)

It was discovered that Pidgin did not properly handle certain malformed messages in the MSN protocol handler. A remote attacker could send a specially crafted message and possibly execute arbitrary code with user privileges.
(CVE-2009-1376).

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