Synopsis

The remote Debian host is missing a security-related update.

Description

Several vulnerabilities have been discovered in the MySQL database server. The Common Vulnerabilities and Exposures project identifies the following problems :

- CVE-2009-4019 Domas Mituzas discovered that mysqld does not properly handle errors during execution of certain SELECT statements with subqueries, and does not preserve certain null_value flags during execution of statements that use the GeomFromWKB function, which allows remote authenticated users to cause a denial of service (daemon crash) via a crafted statement.

- CVE-2009-4030 Sergei Golubchik discovered that MySQL allows local users to bypass certain privilege checks by calling CREATE TABLE on a MyISAM table with modified DATA DIRECTORY or INDEX DIRECTORY arguments that are originally associated with pathnames without symlinks, and that can point to tables created at a future time at which a pathname is modified to contain a symlink to a subdirectory of the MySQL data home directory.

- CVE-2009-4484 Multiple stack-based buffer overflows in the CertDecoder::GetName function in src/asn.cpp in TaoCrypt in yaSSL before 1.9.9, as used in mysqld, allow remote attackers to execute arbitrary code or cause a denial of service (memory corruption and daemon crash) by establishing an SSL connection and sending an X.509 client certificate with a crafted name field.

Solution

Upgrade the mysql-dfsg-5.0 packages.

For the oldstable distribution (etch), these problems have been fixed in version 5.0.32-7etch12

For the stable distribution (lenny), these problems have been fixed in version 5.0.51a-24+lenny3
