Ubuntu 8.04 LTS / 8.10 / 9.04 / 9.10 : pidgin vulnerabilities (USN-886-1)

Critical Nessus Plugin ID 44057

Synopsis

The remote Ubuntu host is missing one or more security-related patches.

Description

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.
