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
Heap-based buffer overflow in Kaspersky Antivirus (KAV) 5.0 and Kaspersky Personal Security Suite 1.1 allows remote attackers to execute arbitrary code via a CAB file with large records after the header.

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.

dbcve analysis · high confidence

Heap-based buffer overflow in Kaspersky Antivirus 5.0 and Kaspersky Personal Security Suite 1.1 when parsing CAB archive files. The vulnerability exists in the CAB file parsing routine which fails to properly validate the size of records following the CAB header, allowing an attacker to overflow the heap and execute arbitrary code via a specially crafted CAB file.

MitigationDisable automatic scanning of CAB archives or block CAB file attachments at the gateway until the product can be upgraded to a supported version, as this legacy software from 2005 is likely past end-of-life and unlikely to receive vendor patches.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify installed Kaspersky product
    Check Programs and Features or run 'kav5' / 'kavpers' from command line to identify which Kaspersky product is installed
    Affected if Any Kaspersky Anti Virus 5.0.x or Kaspersky Personal Security Suite 1.1.x is installed
  2. Confirm exact version number
    Run the installed Kaspersky application and check About or Help menu, or look for version info in the installation directory
    Affected if Version is exactly 5.0 for Anti Virus products or 1.1 for Personal Security Suite
  3. Verify CAB archive scanning is enabled
    Check the real-time protection or on-access scanning settings within the Kaspersky application for CAB file scanning options
    Affected if CAB file scanning, real-time protection, or on-access scanning is enabled and processing CAB archives

User is affected if they have Kaspersky Anti Virus 5.0 or Kaspersky Personal Security Suite 1.1 installed with CAB archive scanning enabled, as the vulnerability triggers when processing specially crafted CAB files.

Mitigation

Disable automatic scanning of CAB archives or block CAB file attachments at the gateway until the product can be upgraded to a supported version, as this legacy software from 2005 is likely past end-of-life and unlikely to receive vendor patches.
