CVE-2021-44224

When operating as a forward proxy, Apache was depending on the setup suspectible to denial of service or Server Side Request forgery.

CVE-2021-44790

A buffer overflow in mod_lua may result in denial of service or potentially the execution of arbitrary code.

For the oldstable distribution (buster), these problems have been fixed in version 2.4.38-3+deb10u7.

For the stable distribution (bullseye), these problems have been fixed in version 2.4.52-1~deb11u2.

We recommend that you upgrade your apache2 packages.

For the detailed security status of apache2 please refer to its security tracker page at: [link moved to references]");
