Fedora 34: 2021-2a10bc68a4 Critical: Path Traversal and RCE in httpd

The Apache HTTP Server is a powerful, efficient, and extensible

web server.

This update addresses CVE-2021-42013. It was found that the fix for

CVE-2021-41773 in Apache HTTP Server 2.4.50 was insufficient. An attacker could

use a path traversal attack to map URLs to files outside the directories

configured by Alias-like directives. If files outside of these directories

are not protected by the usual default configuration "require all denied", these

requests can succeed. If CGI scripts are also enabled for these aliased pathes,

this could allow for remote code execution.
