Technical details
A buffer underwrite (CWE-124) vulnerability exists in Apache HTTP Server's 'ap_regname' function due to a signed character overflow. The flaw is triggered by crafted regular expressions within the server configuration. An attacker with the ability to influence the configuration (such as a local user with .htaccess or main config access) could potentially cause a crash or memory corruption. The issue affects versions 2.4.0 through 2.4.67 and is resolved in version 2.4.68.
