"The mysql_real_connect function doesn't properly handle DNS replies by
copying the IP address into a buffer without any length checking. A
specially crafted DNS reply may therefore be used to cause a buffer
overflow on affected systems.

Note that whether this issue can be exploitable depends on the system
library responsible for the gethostbyname function. The bug finder,
Lukasz Wojtow, explaines this with the following words :

In glibc there is a limitation for an IP address to have only 4 bytes
(obviously), but generally speaking the length of the address comes
with a response for dns query (i know it sounds funny but read rfc1035
if you don't believe). This bug can occur on libraries where
gethostbyname function takes length from dns's response"

"Updated mysql packages that fix various security issues, as well as a
number of bugs, are now available for Red Hat Enterprise Linux 2.1.

MySQL is a multi-user, multi-threaded SQL database server.

A number security issues that affect the mysql server have been
reported :

Oleksandr Byelkin discovered that 'ALTER TABLE ... RENAME' checked the
CREATE/INSERT rights of the old table instead of the new one. The
Common Vulnerabilities and Exposures project (cve.mitre.org) has
assigned the name CVE-2004-0835 to this issue.

Lukasz Wojtow discovered a buffer overrun in the mysql_real_connect
function. In order to exploit this issue an attacker would need to
force the use of a malicious DNS server (CVE-2004-0836).

Dean Ellis discovered that multiple threads ALTERing the same (or
different) MERGE tables to change the UNION could cause the server to
crash or stall (CVE-2004-0837).

Sergei Golubchik discovered that if a user is granted privileges to a
database with a name containing an underscore ('_'), the user also
gains the ability to grant privileges to other databases with similar
names (CVE-2004-0957).

Additionally, the following minor temporary file vulnerabilities were
discovered :

  - Stan Bubroski and Shaun Colley found a temporary file
    vulnerability in the mysqlbug script (CVE-2004-0381). -
    A temporary file vulnerability was discovered in
    mysqld_multi (CVE-2004-0388). - Jeroen van Wolffelaar
    discovered an temporary file vulnerability in the
    mysqlhotcopy script when using the scp method
    (CVE-2004-0457).

All users of mysql should upgrade to these updated packages, which
resolve these issues and also include fixes for a number of small
bugs."
