-------------------------------------------------------------------------------- Fedora Update Notification FEDORA-2021-2a10bc68a4 2021-10-12 23:37:48.488663 --------------------------------------------------------------------------------
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. -------------------------------------------------------------------------------- ChangeLog:
