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.
