Package : apache2
CVE ID : CVE-2020-35452 CVE-2021-26690 CVE-2021-26691 CVE-2021-30641
CVE-2021-31618

Several vulnerabilities have been found in the Apache HTTP server, which
could result in denial of service. In addition the implementation of
the MergeSlashes option could result in unexpected behaviour.

For the stable distribution (buster), these problems have been fixed in
version 2.4.38-3+deb10u5.

We recommend that you upgrade your apache2 packages.

For the detailed security status of apache2 please refer to
its security tracker page at:
https://security-tracker.debian.org/tracker/apache2

these updates to your system and frequently asked questions can be
