SynopsisThe remote Red Hat host is missing one or more security updates.
DescriptionUpdated 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.
SolutionUpdate the affected packages.
