Photon OS 2.0: Httpd PHSA-2021-2.0-0399

critical Nessus Plugin ID 153962

Synopsis

The remote PhotonOS host is missing multiple security updates.

Description

An update of the httpd package has been released.

- A crafted request uri-path can cause mod_proxy to forward the request to an origin server choosen by the remote user. This issue affects Apache HTTP Server 2.4.48 and earlier. (CVE-2021-40438)

- Malformed requests may cause the server to dereference a NULL pointer. This issue affects Apache HTTP Server 2.4.48 and earlier. (CVE-2021-34798)

- A carefully crafted request uri-path can cause mod_proxy_uwsgi to read above the allocated memory and crash (DoS). This issue affects Apache HTTP Server versions 2.4.30 to 2.4.48 (inclusive). (CVE-2021-36160)

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 Linux packages.
