CVE-2012-5615:
MySQL 5.5.19
MariaDB 5.5.28a, 5.3.11, 5.2.13, 5.1.66

Description:
Multiple vulnerabilities exist in MySQL and MariaDB that could allow an attacker to remotely execute code, escalate privileges, and create denial of service conditions. CVE-2012-5611 is the only remotely attackable vulnerability; the latest stable version of MariaDB is not vulnerable.

Severity:
High

Code Execution:
Yes

Impact:
Remote Code Execution
Exploitation of this vulnerability is possible from external vectors. Successful exploitation may grant attackers arbitrary remote code execution within the security context of MySQL.

Mitigation:
Do not give the FILE permission to non-admin users. Utilize the –secure-file-priv option and restrict all FILE operations to a specific location. Additionally, compiling MySQL and MariaDB using a hardened toolchain (employing memory protections such as –z, relro) may benefit efforts to mitigate these vulnerabilities, although this has not been confirmed.
