mysql-dfsg vulnerabilities Detailed Explanation for this Vulnerability Assessment Summary : These remote packages are missing security patches : - libmysqlclient-dev - libmysqlclient12 - mysql-client - mysql-common - mysql-server Description : Several vulnerabilities have been discovered in the MySQL database server. Lukasz Wojtow discovered a potential buffer overflow in the function mysql_real_connect(). A malicious name server could send specially crafted DNS packages which might result in execution of arbitrary code with the database server's rights. However, it is believed that this bug cannot be exploited with the C Standard library (glibc) that Ubuntu uses. (CVE-2004-0836). Dean Ellis noticed a flaw that permits an authorized MySQL user to cause a denial of service (crash or hang) via concurrent execution of certain statements (ALTER TABLE ... UNION=, FLUSH TABLES) on tables of type MERGE (CVE-2004-0837) Some query strings containing a double quote (like MATCH ... AGAINST (' some " query' IN BOOLEAN MODE) ) that did not have a matching closing double quote caused a denial of service (server crash). Again, this is only exploitable by authorized mysql users. (CVE-2004-0956) If a user was granted rights to a database with a name [...] Solution : Upgrade to : - libmysqlclient-dev-4.0.20-2ubuntu1.1 (Ubuntu 4.10) - libmysqlclient12-4.0.20-2ubuntu1.1 (Ubuntu 4.10) - mysql-client-4.0.20-2ubuntu1.1 (Ubuntu 4.10) - mysql-common-4.0.20-2ubuntu1.1 (Ubuntu 4.10) - mysql-server-4.0.20-2ubuntu1.1 (Ubuntu 4.10) Network Security Threat Level: High Networks Security ID: Vulnerability Assessment Copyright: Ubuntu Security Notice (C) 2005 Canonical, Inc. / NASL script (C) 2005 Michel Arboi |
