Vulnerability from variot

Apache HTTP Server versions 2.4.0 to 2.4.46 A specially crafted Digest nonce can cause a stack overflow in mod_auth_digest. There is no report of this overflow being exploitable, nor the Apache HTTP Server team could create one, though some particular compiler and/or compilation option might make it possible, with limited consequences anyway due to the size (a single byte) and the value (zero byte) of the overflow. Apache HTTP Server is an open source web server of the Apache Foundation. The server is fast, reliable and can be expanded through simple APIs. Attackers can use this vulnerability to trigger remote code execution or denial of service attacks. ========================================================================== Ubuntu Security Notice USN-4994-1 June 21, 2021

    "data": "Apache HTTP Server versions 2.4.0 to 2.4.46 A specially crafted Digest nonce can cause a stack overflow in mod_auth_digest. There is no report of this overflow being exploitable, nor the Apache HTTP Server team could create one, though some particular compiler and/or compilation option might make it possible, with limited consequences anyway due to the size (a single byte) and the value (zero byte) of the overflow. Apache HTTP Server is an open source web server of the Apache Foundation. The server is fast, reliable and can be expanded through simple APIs. Attackers can use this vulnerability to trigger remote code execution or denial of service attacks. ==========================================================================\nUbuntu Security Notice USN-4994-1\nJune 21, 2021\n\napache2 vulnerabilities\n==========================================================================\n\nA security issue affects these releases of Ubuntu and its derivatives:\n\n- Ubuntu 21.04\n- Ubuntu 20.10\n- Ubuntu 20.04 LTS\n- Ubuntu 18.04 LTS\n\nSummary:\n\nSeveral security issues were fixed in Apache HTTP Server. \n\nSoftware Description:\n- apache2: Apache HTTP server\n\nDetails:\n\nMarc Stern discovered that the Apache mod_proxy_http module incorrectly\nhandled certain requests.
