Description Murray McAllister 2014-10-21 03:24:49 UTC 
A flaw was found in the way XMPP messages were parsed. A malicious server or possibly a remote attacker could send a crafted XMPP message that would cause Pidgin to send an XMPP message containing arbitrary memory.

Comment 9 Siddharth Sharma 2014-12-16 11:29:48 UTC 
Analysis:

In code of jutil.c, jid being calloced, missing g_strndup would lead to NULL derefs in callers, which wont be something typically leading to info leaks and attacker wont get much even if in any scenario is able to read arbitrary memory.
