Debian There are multiple vulnerabilities in mysql.

Debian Security Advisory DSA-212-1                                  Wichert Akkerman
December 17, 2002

Package        : mysql
Problem type   : multiple problems
Debian-specific: no
CVE references : CAN-2002-1373, CAN-2002-1374, CAN-2002-1375, CAN-2002-1376

While performing an audit of MySQL e-matters found several problems:

* signed/unsigned problem in COM_TABLE_DUMP
  Two sizes were taken as signed integers from a request and then cast
  to unsigned integers without checking for negative numbers. Since the
  resulting numbers where used for a memcpy() operation this could lead
  to memory corruption.

* Password length handling in COM_CHANGE_USER
  When re-authenticating to a different user MySQL did not perform
  all checks that are performed on initial authentication. This created
  two problems:
  * it allowed for single-character password brute forcing (as was fixed in
    February 2000 for initial login) which could be used by a normal user to
    gain root privileges to the database
  * it was possible to overflow the password buffer and force the server
    to execute arbitrary code

* read_rows() overflow in libmysqlclient
  When processing the rows returned by a SQL server there was no check
  for overly large rows or terminating NUL characters. This can be used
  to exploit SQL clients if they connect to a compromised MySQL server.

* read_one_row() overflow in libmysqlclient
  When processing a row as returned by a SQL server the returned field
  sizes were not verified. This can be used to exploit SQL clients if they
  connect to a compromised MySQL server.

For Debian GNU/Linux 3.0/woody this has been fixed in version 3.23.49-8.2
and version 3.22.32-6.3 for Debian GNU/Linux 2.2/potato.

We recommend that you upgrade your mysql packages as soon as possible.

Obtaining updates:

  By hand:
    wget URL
        will fetch the file for you.
    dpkg -i FILENAME.deb
        will install the fetched file.

  With apt:
    deb stable/updates main
        added to /etc/apt/sources.list will provide security updates
