An exploit for a buffer overrun in the AFS dissector was recently released on BugTraq. Ethereal 0.8.14 fixes this and other possibly-exploitable overruns. Also new in 0.8.14 are dissectors for WAP, SIP, AIM/OSCAR, 802.11, GIOP v1.2, and MGCP (plugin). Other dissectors were updated as well. Be sure to upgrade to 0.8.14 as soon as possible.
