Programs that manipulate binary files are common vectors for attacks. A malformed file can trick even well-written and well-tested parsers into executing code that they shouldn't, or corrupting aspects of the user's environment. For example, cvedetails.com, some random website I found from Googling, lists 13 vulnerabilities for Photoshop and 31 for Libreoffice in the last few years.
