Description

Frank Lichtenheld has discovered that texindex insecurely creates temporary files with predictable filenames. This is exploitable if a local attacker were to create symbolic links in the temporary files directory, pointing to a valid file on the filesystem. When texindex is executed, the file would be overwitten with the rights of the user running texindex.

The updated packages have been patched to correct this issue.
