Detailsinfo

A vulnerability classified as critical has been found in Oracle MySQL Server up to 5.5.19 (Database Software). This affects the function MDL_key::mdl_key_init of the component Create Table. The manipulation with an unknown input leads to a memory corruption vulnerability. CWE is classifying the issue as CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

Heap-based buffer overflow in Oracle MySQL 5.5.19 and other versions through 5.5.28, and MariaDB 5.5.28a and possibly other versions, allows remote authenticated users to cause a denial of service (memory corruption and crash) and possibly execute arbitrary code, as demonstrated using certain variations of the (1) USE, (2) SHOW TABLES, (3) DESCRIBE, (4) SHOW FIELDS FROM, (5) SHOW COLUMNS FROM, (6) SHOW INDEX FROM, (7) CREATE TABLE, (8) DROP TABLE, (9) ALTER TABLE, (10) DELETE FROM, (11) UPDATE, and (12) SET PASSWORD commands.

The weakness was published 12/01/2012 by kingcope as confirmed exploit (Website). The advisory is shared at seclists.org. The public release happened without involvement of Oracle. This vulnerability is uniquely identified as CVE-2012-5612 since 10/24/2012. The exploitability is told to be easy. It is possible to initiate the attack remotely. A authentication is required for exploitation. Technical details and a public exploit are known.

A public exploit has been developed by kingcope (kingcope) and been published 1 days after the advisory. The exploit is shared for download at seclists.org. It is declared as proof-of-concept. We expect the 0-day to have been worth approximately $25k-$100k. The vulnerability scanner Nessus provides a plugin with the ID 64421 (FreeBSD : mysql/mariadb/percona server -- multiple vulnerabilities (8c773d7f-6cbb-11e2-b242-c8600054b392)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family FreeBSD Local Security Checks and running in the context l. The commercial vulnerability scanner Qualys is able to test this issue with plugin 19831 (Oracle MySQL January 2013 Critical Patch Update).

Applying a patch is able to eliminate this problem. A possible mitigation has been published 2 months after the disclosure of the vulnerability.

The vulnerability is also documented in the databases at Exploit-DB (23076), Tenable (64421), SecurityFocus (BID 56768†), OSVDB (88064†) and Secunia (SA51427†).
