Description

porkythepig has discovered two vulnerabilities in Microsoft Help Workshop, which can be exploited by malicious people to compromise a user's system.

1) A boundary error when processing .CNT files can be exploited to cause a stack-based buffer overflow via a specially crafted .CNT file.

2) A boundary error when processing .HPJ files can be exploited to cause a stack-based buffer overflow via a specially crafted .HPJ file with an overly long string as the HLP value in the OPTIONS section.

Successful exploitation allows execution of arbitrary code.

The vulnerabilities are confirmed in version 4.03.0002. Other versions may also be affected.

Solution
Do not open untrusted CNT or HPJ files.
