Pidgin is an instant messaging program which can log in to multiple
accounts on multiple instant messaging networks simultaneously.

A stack-based buffer overflow flaw was found in the Pidgin MXit
protocol plug-in. A malicious server or a remote attacker could use
this flaw to crash Pidgin by sending a specially crafted HTTP request.
(CVE-2013-0272)

A buffer overflow flaw was found in the Pidgin Sametime protocol
plug-in. A malicious server or a remote attacker could use this flaw
to crash Pidgin by sending a specially crafted username.
(CVE-2013-0273)

A buffer overflow flaw was found in the way Pidgin processed certain
UPnP responses. A remote attacker could send a specially crafted UPnP
response that, when processed, would crash Pidgin. (CVE-2013-0274)

Red Hat would like to thank the Pidgin project for reporting the above
issues. Upstream acknowledges Daniel Atallah as the original reporter
of CVE-2013-0272.

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."
