CVE-2012-2122 at MITRE

Description

sql/password.c in Oracle MySQL 5.1.x before 5.1.63, 5.5.x before 5.5.24, and 5.6.x before 5.6.6, and MariaDB 5.1.x before 5.1.62, 5.2.x before 5.2.12, 5.3.x before 5.3.6, and 5.5.x before 5.5.23, when running in certain environments with certain implementations of the memcmp function, allows remote attackers to bypass authentication by repeatedly authenticating with the same incorrect password, which eventually causes a token comparison to succeed due to an improperly-checked return value.

Note from the SUSE Security Team

To exploit this security issue, a hardware optimized memcmp is necessary. Our SUSE Linux Enterprise products so far did not ship optimized memcmp functions, so while the buggy code exists in mysql on SUSE Linux Enterprise, it is not affected by this security problem.

openSUSE versions of mariadb or mysql-community-server or other mysql derivatives are affected however.

SUSE Bugzilla entries: 765092 [RESOLVED / FIXED], 766428 [RESOLVED / DUPLICATE]
