Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
Integer underflow in the DHCP server in EMC VMware Workstation before 5.5.5 Build 56455 and 6.x before 6.0.1 Build 55017, Player before 1.0.5 Build 56455 and Player 2 before 2.0.1 Build 55017, ACE before 1.0.3 Build 54075 and ACE 2 before 2.0.1 Build 55017, and Server before 1.0.4 Build 56528 allows remote attackers to execute arbitrary code via a malformed DHCP packet that triggers a stack-based buffer overflow.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

Recommended fix High confidence

Upgrade to VMware Workstation 5.5.5/6.0.1, Player 1.0.5/2.0.1, ACE 1.0.3/2.0.1, or Server 1.0.4 as appropriate for your product line

  1. 1. Identify the exact VMware product (Workstation, Player, ACE, or Server) and version currently installed
  2. 2. For VMware Workstation: upgrade to version 5.5.5 (Build 56455) or 6.0.1 (Build 55017) depending on your major version line
  3. 3. For VMware Player: upgrade to version 1.0.5 (Build 56455) or 2.0.1 (Build 55017) depending on your major version line
  4. 4. For VMware ACE: upgrade to version 1.0.3 (Build 54075) or 2.0.1 (Build 55017) depending on your major version line
  5. 5. For VMware Server: upgrade to version 1.0.4 (Build 56528)
  6. 6. If using VMware ESXi/ESX: contact VMware for patches as specific fixed ESX versions were not listed in the advisory
  7. 7. After upgrade, verify the DHCP server service is running correctly and test that VM networking functions properly
Caveat Upgrading VMware products may require recreation of VM network configurations; ensure backups of VM images exist before performing major version upgrades

Generated from the published advisory — verify against the referenced sources before acting.
