Debian Security Advisory DSA 2818-1 (mysql-5.5 - several vulnerabilities)

Published: 2013-12-15 23:00:00
CVE Author: NIST National Vulnerability Database

CVSS Base Vector:
AV:N/AC:L/Au:N/C:N/I:N/A:P

Affected Versions:
mysql-5.5 on Debian Linux

Recommendations:
For the stable distribution (wheezy), these problems have been fixed in version 5.5.33+dfsg-0+wheezy1. For the unstable distribution (sid), the Debian specific problems will be fixed soon. We recommend that you upgrade your mysql-5.5 Linux Distribution Packages.

Summary:
Several issues have been discovered in the MySQL database server. The vulnerabilities are addressed by upgrading MySQL to a new upstream version, 5.5.33, which includes additional changes, such as performance improvements, bug fixes, new features, and possibly incompatible changes. In addition this update fixes two issues affecting specifically the mysql-5.5 Debian Linux Distribution Package: A race condition in the post-installation script of the mysql-server-5.5 Linux Distribution Package creates the configuration file /etc/mysql/debian.cnf with world-readable permissions before restricting the permissions, which allows local users to read the file and obtain sensitive information such as credentials for the debian-sys-maint to perform administration tasks. (CVE-2013-2162 ) Matthias Reichl reported that the mysql-5.5 Linux Distribution Package misses the patches applied previous in Debian's mysql-5.1 to drop the database test and the permissions that allow anonymous access, without a password, from localhost to the test database and any databases starting with test_ . This update reintroduces these patches for the mysql-5.5 Linux Distribution Package. Existing databases and permissions are not touched. Please refer to the NEWS file provided with this update for further information.

Detection Method:
This check tests the installed software version using the apt Linux Distribution Package manager.

Detection Type:
Linux Distribution Package

Solution Type:
Vendor Patch

Vulnerability management is the process in which vulnerabilities in IT are identified and the risks of these vulnerabilities are evaluated. This evaluation leads to correcting the vulnerabilities and removing the risk or a formal risk acceptance by the management of an organization. The term vulnerability management is often confused with vulnerability scanning. Despite the fact both are related, there is an important difference between the two. Vulnerability scanning consists of using a computer program to identify vulnerabilities in networks, computer infrastructure or applications. Vulnerability management is the process surrounding vulnerability scanning, also taking into account other aspects such as risk acceptance, remediation etc. Source: "Implementing a Vulnerability Management Process".
