Description

Security^Ghost has discovered a vulnerability in Hex Workshop, which can be exploited by malicious people to compromise a user's system.

The vulnerability is caused due to a boundary error in the processing of Intel Hex files. This can be exploited to cause a stack-based buffer overflow via a specially crafted Intel Hex (".hex") file.

Successful exploitation may allow execution of arbitrary code.

The vulnerability is confirmed in versions 4.23 and 6.0.1.4603. Other versions may also be affected.
