Gentoo Linux Security Advisory

Title: MySQL: Multiple vulnerabilities (GLSA 200410-22)
Severity: high
Exploitable: remote
Date: October 24, 2004
Bug(s): #67062
ID: 200410-22

Synopsis

Several vulnerabilities including privilege abuse, Denial of Service, and potentially remote arbitrary code execution have been discovered in MySQL.

Background

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

Affected Packages

Package: dev-db/mysql
Vulnerable: < 4.0.21
Unaffected: >= 4.0.21
Architectures: All supported architectures


Description

The following vulnerabilities were found and fixed in MySQL: Oleksandr Byelkin found that ALTER TABLE ... RENAME checks CREATE/INSERT rights of the old table instead of the new one (CAN-2004-0835). Another privilege checking bug allowed users to grant rights on a database they had no rights on. Dean Ellis found a defect where multiple threads ALTERing the MERGE tables to change the UNION could cause the server to crash (CAN-2004-0837). Another crash was found in MATCH ... AGAINST() queries with missing closing double quote. Finally, a buffer overrun in the mysql_real_connect function was found by Lukasz Wojtow (CAN-2004-0836).

Impact

The privilege checking issues could be used by remote users to bypass their rights on databases. The two crashes issues could be exploited by a remote user to perform a Denial of Service attack on MySQL server. The buffer overrun issue could also be exploited as a Denial of Service attack, and may allow to execute arbitrary code with the rights of the MySQL daemon (typically, the "mysql" user).

Workaround

There is no known workaround at this time.

Resolution

All MySQL users should upgrade to the latest version:
Code:
# emerge sync
# emerge -pv ">=dev-db/mysql-4.0.21"
# emerge ">=dev-db/mysql-4.0.21"
