The scanning engine in VirusBlokAda VBA32 Personal Antivirus 3.12.8.x allows remote attackers to cause a denial of service (memory corruption and application crash) via a malformed RAR archive.

VirusBlokAda VBA32 3.12.8.5, 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.

VirusBlokAda Vba32 AntiVirus 3.12.2 uses weak permissions (Everyone:Write) for its installation directory, which allows local users to gain privileges by replacing application programs, as demonstrated by replacing vba32ldr.exe.
