Summary:

Several security issues were fixed in Apache HTTP Server.

Software Description:
- apache2: Apache HTTP server

Details:

It was discovered that the Apache HTTP Server incorrectly handled certain
forward proxy requests. A remote attacker could use this issue to cause
the server to crash, resulting in a denial of service, or possibly perform
a Server Side Request Forgery attack. (CVE-2021-44224)

handled memory in the multipart parser. A remote attacker could use this
issue to cause the server to crash, resulting in a denial of service, or
possibly execute arbitrary code. (CVE-2021-44790)
