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
Buffer overflow in Cisco Advanced Recording Format (ARF) player T27 LD before SP32 EP16, T28 before T28.12, and T29 before T29.2 allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption and application crash) via a crafted .arf file that triggers improper LZW decompression, aka Bug ID CSCuj87565.

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

A buffer overflow vulnerability exists in Cisco's Advanced Recording Format (ARF) player software (T27, T28, and T29 product lines) due to improper LZW decompression when processing crafted .arf files. Attackers can exploit this by tricking users into opening malicious .arf files, potentially achieving arbitrary code execution or causing memory corruption and application crashes.

MitigationApply the vendor-supplied patches: upgrade to T27 SP32 EP16, T28 T28.12, or T29.2 or later. Until patches are applied, avoid opening .arf files from untrusted sources.

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 if Cisco Webex ARF Player is installed
    Check the installed programs list in Windows Control Panel > Programs and Features, or look for Webex ARF Player executable (arfplay.exe or similar) in Program Files directories. Also check for Webex Recording Format Player entry.
    Affected if The software is present on the system.
  2. Determine the installed version of the ARF Player
    Right-click the installed ARF player executable, select Properties, and check the Version tab. Alternatively, open the Webex player and look for About or Version information in the Help menu.
    Affected if The version displays as t27ld, t28, or t29 (any build).
  3. Compare installed version against vulnerable releases
    If version shows t27ld, ensure it is after SP32 EP16. For t28, ensure it is after T28.12. For t29, ensure it is after 29.2. Earlier versions or unspecified build numbers indicate potential vulnerability.
    Affected if Version is t27ld (any version before SP32 EP16), t28 (any version before T28.12), or t29 (any version before 29.2).
  4. Verify .arf file association with the player
    Right-click any .arf file, select Properties, and check the Opens with field. Or go to Default Programs > Associate a file type with a program to see if .arf is linked to Webex ARF Player.
    Affected if The .arf file extension is associated with a vulnerable version of the Cisco Webex ARF Player.

If Cisco Webex ARF Player versions t27ld (before SP32 EP16), t28 (before T28.12), or t29 (before 29.2) are installed and handle .arf files, the system is affected by this vulnerability.
