Package        : mysql-dfsg-4.1
Vulnerability  : buffer overflow
Problem type   : remote
Debian-specific: no
CVE ID         : CAN-2005-2558
BugTraq ID     : 14509

A stack-based buffer overflow in the init_syms function of MySQL, a
popular database, has been discovered that allows remote authenticated
users who can create user-defined functions to execute arbitrary code
via a long function_name field.  The ability to create user-defined
functions is not typically granted to untrusted users.

The following vulnerability matrix explains which version of MySQL in
which distribution has this problem fixed:

                     woody              sarge              sid
mysql             3.23.49-8.14           n/a               n/a
mysql-dfsg            n/a          4.0.24-10sarge1    4.0.24-10sarge1
mysql-dfsg-4.1        n/a          4.1.11a-4sarge2        4.1.14-2
mysql-dfsg-5.0        n/a                n/a            5.0.11beta-3

This update only covers binary packages for the big endian MIPS
architecture that was mysteriously forgotton in the earlier update.

We recommend that you upgrade your mysql-dfsg-4.1 packages.
