Description Josh Bressers 2005-09-29 21:01:40 UTC

+++ 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:
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=328365

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.

This issue should also affect FC3
