Description: Sergio Alvarez has reported some vulnerabilities in Norman Antivirus products, which can be exploited by malware to bypass certain scanning functionality and by malicious people to cause a DoS (Denial of Service) or compromise a vulnerable system. 1) A boundary error when processing ACE archives can be exploited to cause a buffer overflow when e.g. scanning a specially crafted ACE archive. 2) Three boundary errors when processing LZH archives can be exploited to cause a buffer overflow when e.g. scanning a specially crafted LZH archive. Successful exploitation of the vulnerabilities allow execution of arbitrary code. 3) A divide-by-zero error when processing DOC files can be exploited to to e.g. crash the application via a specially crafted DOC file. 4) An error within the processing of DOC files can be exploited to e.g. cause malware in a specially crafted DOC file to pass the scanning functionality undetected. The vulnerabilities are reported in version 5.90 of the scanner engine. Other versions may also be affected. Solution: Vulnerabilities #3 and #4 have reportedly been fixed in version 5.91.02 of the scanner engine.
