                    Remote Code Execution in Apache HTTP Server 2.4.49 and

Update apache24 to 2.4.51

Fixed in Apache HTTP Server 2.4.51

critical: Path Traversal and Remote Code Execution in Apache HTTP Server 2.=
4.49
and 2.4.50 (incomplete fix of CVE-2021-41773) (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 rem=
ote
code execution.

    This issue only affects Apache 2.4.49 and Apache 2.4.50 and not earlier
versions.
