3. Description:

 

Pidgin is an instant messaging program which can log in to multiple

accounts on multiple instant messaging networks simultaneously.

 

A heap-based buffer overflow flaw was found in the way Pidgin processed

certain HTTP responses. A malicious server could send a specially crafted

HTTP response, causing Pidgin to crash or potentially execute arbitrary

code with the permissions of the user running Pidgin. (CVE-2013-6485)

 

Multiple heap-based buffer overflow flaws were found in several protocol

plug-ins in Pidgin (Gadu-Gadu, MXit, SIMPLE). A malicious server could send

a specially crafted message, causing Pidgin to crash or potentially execute

arbitrary code with the permissions of the user running Pidgin.

(CVE-2013-6487, CVE-2013-6489, CVE-2013-6490)

 

Multiple denial of service flaws were found in several protocol plug-ins in

Pidgin (Yahoo!, XMPP, MSN, stun, IRC). A remote attacker could use these

flaws to crash Pidgin by sending a specially crafted message.

(CVE-2012-6152, CVE-2013-6477, CVE-2013-6481, CVE-2013-6482, CVE-2013-6484,

CVE-2014-0020)

 

It was found that the Pidgin XMPP protocol plug-in did not verify the

origin of "iq" replies. A remote attacker could use this flaw to spoof an

"iq" reply, which could lead to injection of fake data or cause Pidgin to

crash via a NULL pointer dereference. (CVE-2013-6483)

 

A flaw was found in the way Pidgin parsed certain HTTP response headers.

A remote attacker could use this flaw to crash Pidgin via a specially

crafted HTTP response header. (CVE-2013-6479)

 

It was found that Pidgin crashed when a mouse pointer was hovered over a

long URL. A remote attacker could use this flaw to crash Pidgin by sending

a message containing a long URL string. (CVE-2013-6478)

 

Red Hat would like to thank the Pidgin project for reporting these issues.

Upstream acknowledges Thijs Alkemade, Robert Vehse, Jaime Breva Ribes,

Jacob Appelbaum of the Tor Project, Daniel Atallah, Fabian Yamaguchi and

Christian Wressnegger of the University of Goettingen, Matt Jones of

Volvent, and Yves Younan, Ryan Pentney, and Pawel Janic of Sourcefire VRT

as the original reporters of these issues.

 

All pidgin users are advised to upgrade to these updated packages, which

contain backported patches to correct these issues. Pidgin must be

restarted for this update to take effect.
