CVE-2006-0642
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 · uneditedTrend Micro ServerProtect 5.58, and possibly InterScan Messaging Security Suite and InterScan Web Security Suite, have a default configuration setting of "Do not scan compressed files when Extracted file count exceeds 500 files," which may be too low in certain circumstances, which allows remote attackers to bypass anti-virus checks by sending compressed archives containing many small files. NOTE: since this is related to a configuration setting that has an operational impact that might vary depending on the environment, and the product is claimed to report a message when the compressed file exceeds specified limits, perhaps this should not be included in CVE.
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 confidenceTrend Micro ServerProtect 5.58 and related products have a default configuration threshold that stops scanning compressed files when they contain more than 500 extracted files. This threshold can be exploited by remote attackers who craft archives with many small files to bypass anti-virus detection.

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 Trend Micro productReview installed software on the system to determine if Trend Micro Interscan Messaging Security Suite, Trend Micro Interscan Web Security Suite, or Trend Micro ServerProtect 5.58 is presentAffected if Any of these products is installed, the environment may be vulnerable
-
Locate the Extracted file count threshold settingAccess the product configuration console or configuration files for the installed Trend Micro product and locate the setting related to 'Extracted file count' or 'Maximum extracted files' threshold for archive scanningAffected if The setting exists and is currently configured at the default threshold of 500 files
-
Verify the current threshold valueExamine the current value of the Extracted file count threshold configuration settingAffected if The threshold is set to 500 (the default vulnerable value) or remains at the default setting without being explicitly increased
-
Check if archive scanning is enabledConfirm that compressed file scanning or archive scanning features are enabled in the product configurationAffected if Archive scanning is enabled AND the extracted file count threshold remains at the default 500 value, the product can be bypassed by archives containing more than 500 files
A system is affected if it runs any of the listed Trend Micro products with the default Extracted file count threshold of 500 still in place and archive scanning enabled.

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 dataIncrease the 'Extracted file count' threshold in the product configuration to a value appropriate for the environment, or disable this limit for high-security zones.
