Encrypt3d.M!nd 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 creation of certain window text messages. This can be exploited to cause a heap-based buffer overflow by e.g. tricking the user into selecting a color map file (".cmap") containing an overly long quoted hex sequence.
Successful exploitation may allow execution of arbitrary code.
The vulnerability is confirmed in version 18.104.22.16888. Other versions may also be affected.
Solution: Upgrade to version 6.0.1, which does not seem affected.
