Description Tom Lane 2005-03-11 15:30:53 UTC

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.
