| Description: | Description:
The remote host is missing an update to postgresql
announced via advisory MDKSA-2002:062-1.
Vulnerabilities were discovered in the Postgresql relational database
by Mordred Labs. These vulnerabilities are buffer overflows in the
rpad(), lpad(), repeat(), and cash_words() functions. The Postgresql
developers also fixed a buffer overflow in functions that deal with
time/date and timezone.
Finally, more buffer overflows were discovered by Mordred Labs in the
7.2.2 release that are currently only fixed in CVS. These buffer
overflows exist in the circle_poly(), path_encode(), and path_addr()
functions.
In order for these vulnerabilities to be exploited, an attacker must be
able to query the server somehow. However, this cannot directly lead
to root privilege because the server runs as the postgresql user.
Prior to upgrading, users should dump their database and retain it as
backup. You can dump the database by using:
$ pg_dumpall > db.out
If you need to restore from the backup, you can do so by using:
$ psql -f db.out template1
Update:
The previous update missed a few small fixes, including a buffer overflow
in the cash_words() function that allows local users to cause a DoS and
possibly execute arbitrary code via a malformed argument in Postgresql 7.2
and earlier. As well, buffer overflows in the TZ and SET TIME ZONE
environment variables for Postgresql 7.2.1 and earlier can allow local
users to cause a DoS and possibly execute arbitrary code.
Affected versions: 7.2, 8.0, 8.1, 8.2, 9.0,
Single Network Firewall 7.2
Solution:
To upgrade automatically use MandrakeUpdate or urpmi. The verification
of md5 checksums and GPG signatures is performed automatically for you.
