Frank Lichtenheld discovered that the ‘texindex’ program created temporary files in an insecure manner. This could allow a symlink attack to create or overwrite arbitrary files with the privileges of the user running texindex.
Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
