Description Josh Bressers 2005-03-29 15:16:24 UTC

The following issues need to be fixed in the RHEL3 LACD mysql-server package:

(CAN-2005-0711)
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.


(CAN-2005-0709 CAN-2005-0710)
Description of problem:
MySQL allows users with very low privileges to create user-defined
functions that reference code in loadable shared libraries.  Obviously
this creates a risk of users being able to cause the server to execute
arbitrary code.  There are some rather ad-hoc restrictions intended to
prevent misuse of the feature, but Stefano Di Paola found two
different ways to create problems anyway: you can call an arbitrary
function belonging to any standard system library, and you can
circumvent the check against giving an absolute path to a library.

Comment 1 foobarra 2005-03-30 13:42:42 UTC

For the casual reader, currently, RHEL-3 versions of the MySQL server have not
been patched for the vulnerability announced in:

http://rhn.redhat.com/errata/RHSA-2005-334.html

The only packages released in this errata for RHEL-3 were the client, headers,
and benchmark - the mysql-server RPM was not included, and is still vulnerable
to this attack.
