CVE-2002-0401
SMB dissector in Ethereal 0.9.3 and earlier allows remote attackers to cause a denial of service (crash) or execute arbitrary code via malformed packets that cause Ethereal to dereference a NULL pointer.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (5.51%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
