CVE-2012-2386 is an integer overflow vulnerability in the phar extension of PHP versions before 5.3.14 and 5.4.4. This flaw, specifically within the phar_parse_tarfile function, allows remote attackers to trigger a heap-based buffer overflow via a crafted tar file. With a CVSS score of 7.5, this vulnerability is considered highly severe, enabling denial of service (application crash) and potentially arbitrary code execution without authentication. While not listed in CISA KEV, exploit code for a heap overflow (EDB-17201) exists, though there is no evidence of active exploitation, Metasploit modules, or significant community discussion.
