CVE-2013-6483
Published:February 06, 2014
Updated:May 17, 2026
The XMPP protocol plugin in libpurple in Pidgin before 2.10.8 does not properly determine whether the from address in an iq reply is consistent with the to address in an iq request, which allows remote attackers to spoof iq traffic or cause a denial of service (NULL pointer dereference and application crash) via a crafted reply.
