Description
Scribus before 1.6.7 contains an out-of-bounds write vulnerability in the importdrw Micrografx Draw plugin that uses an unvalidated y offset to select image scanlines. Attackers can craft a DRW file that, when imported by a user, writes decoded bitmap data outside the heap image buffer, causing crashes or code execution.
