CVE-2006-3961· NVD / CVE Program· CNA mitre

Buffer overflow in McSubMgr ActiveX control (mcsubmgr.dll) in McAfee Security Center 6.0.23 for Internet Security Suite 2006, Wireless Home

Noroxi assessment

Priority: Monitor (action score 37/100)

  • A ready-made attack module is public (Metasploit); exploiting it takes no special expertise.
  • Probability of exploitation in the next 30 days: 34.3% (FIRST EPSS); higher than 98.3% of all records.
  • According to the record, no fixed version is available yet.

Low priority for now. Update when a fix is released; follow the vendor's advisory.

No credits in the CNA record.

Variant candidates

Same product, same weakness class, within 18 months. If the patch missed the root cause, the sibling bug is here.

No nightly-computed relations.

Chain candidates

An authentication bypass and a privilege-requiring bug in the same product, published close together: combined they may become an unauthenticated path.
