CVE-2004-0176
Multiple buffer overflows in Ethereal 0.8.13 to 0.10.2 allow remote
attackers to cause a denial of service and possibly execute arbitrary
code via the (1) NetFlow, (2) IGAP, (3) EIGRP, (4) PGM, (5) IrDA, (6)
BGP, (7) ISUP, or (8) TCAP dissectors.

CVE-2004-0365
The dissect_attribute_value_pairs function in packet-radius.c for
Ethereal 0.8.13 to 0.10.2 allows remote attackers to cause a denial of
service (crash) via a malformed RADIUS packet that triggers a null
dereference.

CVE-2004-0367
Ethereal 0.10.1 to 0.10.2 allows remote attackers to cause a denial of
service (crash) via a zero-length Presentation protocol selector.");
