Ubuntu releases notice USN-2022-1234-1 for Transmission addressing significant vulnerabilities and updates for Ubuntu 20.04.
Updated pidgin packages that fix multiple security issues are now available for Red Hat Enterprise Linux 6

Solution

Before applying this update, make sure all previously-released errata relevant to your system have been applied.

This update is available via the Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at https://access.redhat.com/kb/docs/DOC-11259

Summary

Pidgin is an instant messaging program which can log in to multiple accounts on multiple instant messaging networks simultaneously.
An input sanitization flaw was found in the way the AOL Open System for Communication in Realtime (OSCAR) protocol plug-in in Pidgin, used by the AOL ICQ and AIM instant messaging systems, escaped certain UTF-8 characters. A remote attacker could use this flaw to crash Pidgin via a specially-crafted OSCAR message. (CVE-2011-4601)
Multiple NULL pointer dereference flaws were found in the Jingle extension of the Extensible Messaging and Presence Protocol (XMPP) protocol plug-in in Pidgin. A remote attacker could use these flaws to crash Pidgin via a specially-crafted Jingle multimedia message. (CVE-2011-4602)
Red Hat would like to thank the Pidgin project for reporting these issues. Upstream acknowledges Evgeny Boger as the original reporter of CVE-2011-4601, and Thijs Alkemade as the original reporter of CVE-2011-4602.
All Pidgin users should upgrade to these updated packages, which contain backported patches to resolve these issues. Pidgin must be restarted for this update to take effect.
