Description

Updated apache packages fix security vulnerabilities

The updated packages fix a security vulnerabilities:

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 (CVE-2021-41524).

A flaw was found in a change made to path normalization in Apache HTTP

Server 2.4.49. An attacker could use a path traversal attack to map URLs

to files outside the expected document root. If files outside of the

document root are not protected by "require all denied" these requests can

succeed. Additionally this flaw could leak the source of interpreted files

like CGI scripts. This issue is known to be exploited in the wild. This

issue only affects Apache 2.4.49 and not earlier versions (CVE-2021-41773).
