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.

Comment 1 Josh Bressers 2005-09-29 21:03:00 UTC
This issue should also affect FC3

Comment 3 Fedora Update System 2005-10-14 15:58:03 UTC
From User-Agent: XML-RPC

texinfo-4.8-4.1 has been pushed for FC4, which should resolve this issue.  If these problems are still present in this version, then please make note of it in this bug report.
