A flaw was found in httpd's mod_auth_digest module. A use-after-free vulnerability allows an unauthenticated remote attacker to corrupt the server's authentication state by submitting concurrent Digest authentication requests. This issue occurs when specific configuration settings, such as nonce checking (AuthDigestNcCheck) or zero-duration nonce lifetimes (AuthDigestNonceLifetime), are enabled.
