High severity, CVSS 7.5. EPSS: 2.6% chance of exploitation in the next 30 days.

NOTE: this issue has been disputed by the vendor. Symantec Norton AntiVirus 2002 allows remote attackers to send viruses that bypass the e-mail scanning via a NULL character in the MIME header before the virus. NOTE: the vendor has disputed this issue, acknowledging that the initial scan is bypassed, but the AutoProtect feature would detect the virus before it is executed
