Multiple interpretation error in ArcaVir 2005 package 2005-06-21 allows remote attackers to bypass virus scanning via a file such as BAT, HTML, and EML with an "MZ" magic byte sequence which is normally associated with EXE, which causes the file to be treated as a safe type that could still be executed as a dangerous file type by applications on the end system, as demonstrated by a "triple headed" program that contains EXE, EML, and HTML content, aka the "magic byte bug."

Security readout for executives and security teams

CVE-2005-3370 is an antivirus scanning bypass in ArcaVir 2005 package 2005-06-21. A specially structured file could be interpreted differently by the scanner and by endpoint applications, letting dangerous content avoid detection. This matters mainly where the named legacy product still protects email, web, or file-transfer paths. Exposure is likely limited to environments still using ArcaVir 2005 package 2005-06-21 or relying on historical scan results from that product. The source data does not identify broader affected versions, platforms, or CPEs. Prioritize this if legacy ArcaVir remains in production or archived gateways still influence trust decisions. Otherwise, treat it as a legacy exposure review item rather than an emergency response issue. Mitigation focus: Check vendor guidance for ArcaVir 2005 package 2005-06-21.; Replace unsupported legacy antivirus scanning components.; Use layered attachment and content inspection controls..
