Eric Romang discovered a temporary file vulnerability in a script
accompanied with MySQL, a popular database, that allows an attacker to
execute arbitrary SQL commands when the server is installed or
updated.
The old stable distribution (woody) as well as mysql-dfsg are not
affected by this problem.
For the stable distribution (sarge) this problem has been fixed in
version 4.1.11a-4sarge1.
For the unstable distribution (sid) this problem has been fixed in
version 4.1.12 for mysql-dfsg-4.1 and 5.0.11beta-3 of mysql-dfsg-5.0.
We recommend that you upgrade your mysql packages.
