Symantec AntiVirus (SAV) 10, when Internet Explorer 6 or 7 is used, allows remote attackers to bypass detection of malware in an HTML document by placing an MZ header (aka "EXE info") at the beginning, and modifying the filename to have (1) no extension, (2) a .txt extension, or (3) a .jpg extension, as demonstrated by a document containing a CVE-2006-5745 exploit.

Security readout for executives and security teams

This is a legacy antivirus detection bypass. Under specific conditions, Symantec AntiVirus 10 with Internet Explorer 6 or 7 could fail to detect malicious HTML disguised with executable-like content and misleading filenames. The main concern is old, unsupported desktop environments still relying on this control. Exposure appears limited to legacy endpoints running Symantec AntiVirus 10 with Internet Explorer 6 or 7. Organizations without those components are unlikely to be affected by this specific issue. Treat this as a legacy-risk cleanup item unless those old products remain in production. If present, prioritize removal because the control could miss web-delivered malware under documented conditions. Mitigation focus: Identify and retire Internet Explorer 6 and 7 from managed endpoints.; Upgrade or replace Symantec AntiVirus 10 with supported endpoint protection.; Check Symantec or Broadcom guidance for historical fixes or migration advice..
