TITLE

Apache HTTP Server  of  mod_auth_digest  Stack Overflow Vulnerability in

DESCRIPTION

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 apache2 vulnerabilities ========================================================================== A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 21.04 - Ubuntu 20.10 - Ubuntu 20.04 LTS - Ubuntu 18.04 LTS Summary: Several security issues were fixed in Apache HTTP Server.
