CVE-2012-5612

44
FAUCET Score

CVE-2012-5612 describes a heap-based buffer overflow vulnerability in Oracle MySQL versions through 5.5.28 and MariaDB versions through 5.5.28a, affecting products from Canonical and SUSE. This flaw allows remote authenticated users to trigger a denial of service (memory corruption and crash) and potentially execute arbitrary code through various SQL commands. With a CVSS score of 6.5 (medium severity) and an EPSS score indicating high exploitability potential, the vulnerability has a network attack vector, low attack complexity, and can lead to partial confidentiality, integrity, and availability impacts. While not listed on the KEV catalog or Hot List, a Proof-of-Concept exploit is publicly available on ExploitDB, though there is no evidence of active exploitation, Metasploit modules, or significant community discussion or media coverage.
