SMB Mailslot, H.245, MGCP, Q.931, RPC, GSM and SMB NETLOGON dissectors
are vulnerable to pointer handling errors.
The LMP, KINK,
MGCP, RSVP, SRVLOC, EIGRP, MEGACO, DLSw, NCP and L2TP dissectors are
vulnerable to looping problems.
The Telnet and DHCP dissectors
could abort.
The TZSP, Bittorrent, SMB, MGCP and ISUP
dissectors could cause a segmentation fault.
The WSP, 802.3
Slow protocols, BER, SMB Mailslot, SMB, NDPS, IAX2, RADIUS, SMB PIPE,
