--

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)

Pidgin must be restarted for this update to take effect.
