Description Josh Bressers 2005-03-28 13:41:23 EST
+++ This bug was initially created as a clone of Bug #150868 +++

Description of problem:
If an authenticated user has CREATE TEMPORARY TABLE privileges on any
existent database, a symlink attack is possible. 

Reported to vulnwatch.org by Stefano Di Paola on 11 Mar 2005

Version-Release number of selected component (if applicable):
mysql-4.1.7-5.RHEL4.1

How reproducible:
Requires some luck to guess name that will be used for temp file,
but unfortunately that's fairly predictable.

Steps to Reproduce:
1.  See vulnwatch report.

Additional info:
This is fixed in 4.1.10a, which we should upgrade to anyway as it
contains numerous other bug fixes.

The errata release is incomplete for RHEL-3, and does not include a patched
mysql-server package...
Comment 6 Mark J. Cox (Product Security) 2005-03-30 08:45:33 EST
On RHEL3, mysql-server is part of "Extras", see bug 152437 for tracking.
