Description

Angry IP Scanner 3.5.3 contains a buffer overflow vulnerability in the preferences dialog that allows local attackers to crash the application by supplying an excessively large string. Attackers can generate a file containing a massive buffer of repeated characters and paste it into the unavailable value field in the display preferences to trigger a denial of service.
