CVE-2005-3922
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 · uneditedHeap-based buffer overflow in pskcmp.dll in Panda Software Antivirus library allows remote attackers to execute arbitrary code via a crafted ZOO archive.
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 confidenceHeap-based buffer overflow in pskcmp.dll, a Panda Software Antivirus library component, allows remote code execution when the antivirus scans a specially crafted ZOO archive file. The overflow occurs in heap memory during archive parsing, enabling attackers to inject and execute arbitrary code.

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 checksWork through these to decide whether this CVE applies to you.
-
Identify installed Panda antivirus productCheck Add/Remove Programs or program files directory for Panda Software antivirus installations (look for Panda Activescan, Panda Antivirus, Panda Antivirus Platinum, Panda Businessecure Antivirus, Panda Clientshield, Panda Enterprisecure, Panda Exchangesecure, or Panda Filesecure)Affected if Any of the listed Panda products are installed (versions 5.0 or lower for Activescan, 2.0 or lower for Antivirus/Platinum, or any version for Businessecure/Clientshield/Enterprisecure/Exchangesecure/Filesecure)
-
Verify product version numberLocate the installed Panda product in program files, check version info in the executable or DLL properties, or run 'reg query' for the product version in Windows Registry under HKLM\SOFTWARE\Panda SoftwareAffected if Version is 5.0 or lower for Activescan, 2.0 or lower for Antivirus or Platinum, or any version for the all-versions products listed
-
Confirm pskcmp.dll existsSearch for pskcmp.dll in the Panda installation directory (commonly C:\Program Files\Panda Software or subdirectories)Affected if The vulnerable DLL file pskcmp.dll is present in the Panda installation folder
-
Check if ZOO archive scanning is enabledOpen Panda antivirus configuration and look for archive scanning settings; verify if ZOO archive format support is enabled in the scan settingsAffected if ZOO archive scanning/parsing is enabled in the antivirus configuration
A user is affected if any of the listed Panda products are installed with a version matching the affected ranges AND the pskcmp.dll component exists AND ZOO archive scanning is enabled, allowing the specially crafted ZOO file to trigger the heap overflow during antivirus scanning.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataUpdate Panda Software Antivirus to a version that patches this vulnerability, or if unsupported, replace with a current antivirus solution and implement email/gateway filtering to block ZOO archive attachments.
