Azure Linux 3.0 Security Update: httpd / mod_http2 (CVE-2022-37436)

medium Nessus Plugin ID 236827

Synopsis

The remote Azure Linux host is missing one or more security updates.

Description

The version of httpd / mod_http2 installed on the remote Azure Linux 3.0 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the CVE-2022-37436 advisory.

 - Prior to Apache HTTP Server 2.4.55, a malicious backend can cause the response headers to be truncated early, resulting in some headers being incorporated into the response body. If the later headers have any security purpose, they will not be interpreted by the client. (CVE-2022-37436)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected packages.
