--------------------------------------------------------------------------------
Name : httpd
Product : Fedora 34
Version : 2.4.51
Release : 1.fc34
URL : https://httpd.apache.org/
Summary : Apache HTTP Server
Description :
The Apache HTTP Server is a powerful, efficient, and extensible
web server.
--------------------------------------------------------------------------------
Update Information:
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.
