TITLE

Apache HTTP Server Denial of Service Vulnerability (CNVD-2022-09237)

Trust: 0.6

sources: CNVD: CNVD-2022-09237

DESCRIPTION

While fuzzing the 2.4.49 httpd, a new null pointer dereference was detected during HTTP/2 request processing, allowing an external source to DoS the server. This requires a specially crafted request. The vulnerability was recently introduced in version 2.4.49. No exploit is known to the project. Apache HTTP Server is an open source web server of the Apache Foundation in the United States. The server is fast, reliable and extensible through a simple API. No detailed vulnerability details are currently provided. - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Gentoo Linux Security Advisory GLSA 202208-20 - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - https://security.gentoo.org/ - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Severity: High Title: Apache HTTPD: Multiple Vulnerabilities Date: August 14, 2022 Bugs: #813429, #816399, #816864, #829722, #835131, #850622 ID: 202208-20 - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Synopsis ======= Multiple vulnerabilities have been discovered in Apache Webserver, the worst of which could result in remote code execution.
