Synopsis :

The remote Red Hat host is missing one or more security updates.

Description :

Updated mysql packages that fix three security issues are now
available for Red Hat Enterprise Linux 4.

The Red Hat Security Response Team has rated this update as having
moderate security impact. Common Vulnerability Scoring System (CVSS)
base scores, which give detailed severity ratings, are available for
each vulnerability from the CVE links in the References section.

MySQL is a multi-user, multi-threaded SQL database server. It consists
of the MySQL server daemon (mysqld) and many client programs and
libraries.

It was found that the MySQL PolyFromWKB() function did not sanity
check Well-Known Binary (WKB) data. A remote, authenticated attacker
could use specially crafted WKB data to crash mysqld. This issue only
caused a temporary denial of service, as mysqld was automatically
restarted after the crash. (CVE-2010-3840)

A flaw was found in the way MySQL processed certain alternating READ
requests provided by HANDLER statements. A remote, authenticated
attacker could use this flaw to provide such requests, causing mysqld
to crash. This issue only caused a temporary denial of service, as
mysqld was automatically restarted after the crash. (CVE-2010-3681)

A directory traversal flaw was found in the way MySQL handled the
parameters of the MySQL COM_FIELD_LIST network protocol command. A
remote, authenticated attacker could use this flaw to obtain
descriptions of the fields of an arbitrary table using a request with
a specially crafted table name. (CVE-2010-1848)

All MySQL users are advised to upgrade to these updated packages,
which contain backported patches to correct these issues. After
installing this update, the MySQL server daemon (mysqld) will be
restarted automatically.
