Description Josh Bressers 2005-09-29 17:01:40 EDT
+++ This bug was initially created as a clone of Bug #169583 +++

The texindex command uses predictable temporary filenames.  This could allow a
rogue local user to create a symlink which would cause texindex to overwrite
various files the user running texindex has write access to.

There is more informatin in the Debian bug:

No patch exists yet.

This issue seems to be mitigated by the fact that texindex will only use a
temporary file when the file being processed is over 50,000 lines.
