Vulnerability in GIOP dissector in Ethereal before 0.9.3 allows remote attackers to cause a denial of service (memory consumption).

DNS dissector in Ethereal before 0.9.3 allows remote attackers to cause a denial of service (CPU consumption) via a malformed packet that causes Ethereal to enter an infinite loop.

Buffer overflow in X11 dissector in Ethereal 0.9.3 and earlier allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code while Ethereal is parsing keysyms.

The ASN.1 parser in Ethereal 0.9.2 and earlier allows remote attackers to cause a denial of service (crash) via a certain malformed packet, which causes Ethereal to allocate memory incorrectly, possibly due to zero-length fields.
