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 overflow in the Real-Time Information Server (RIS) Data Collector service (RisDC.exe) in Cisco Unified Communications Manager (CUCM, formerly CallManager) before 20070711 allow remote attackers to execute arbitrary code via crafted packets, resulting in a heap-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 Moderate confidence

Upgrade to a version released after July 2007. Specific fixed releases: CUCM 3.3(5)sr3+, 4.1(3)sr5+, 4.2(3)sr2+, 5.1(3)+, or 4.3(2)+

  1. 1. Identify the current installed version of Cisco Unified Communications Manager (CUCM) or CallManager using the CLI command: 'show version detailed'
  2. 2. Access the Cisco Unified Communications Manager administration interface
  3. 3. Navigate to the Cisco Unified Communications Manager version compatibility matrix to verify upgrade paths between major releases
  4. 4. Plan an upgrade to a fixed release version. Based on the 'before 20070711' patch date, any version released after July 11, 2007 should contain the fix
  5. 5. For Unified CallManager 3.3.x: upgrade to version 3.3(5)sr3 or later
  6. 6. For Unified CallManager 4.1.x: upgrade to version 4.1(3)sr5 or later
  7. 7. For Unified CallManager 4.2.x: upgrade to version 4.2(3)sr2 or later
  8. 8. For Unified CallManager 5.1.x: upgrade to version 5.1(3) or later
Caveat Major version upgrades may require significant testing and could introduce changes to dial plan,铃声, or device configurations; consult Cisco compatibility matrix before upgrading across major releases
