Photon OS 4.0: Haproxy PHSA-2021-4.0-0092

high Nessus Plugin ID 153037

Synopsis

The remote PhotonOS host is missing multiple security updates.

Description

An update of the haproxy package has been released.

- An issue was discovered in HAProxy 2.2 before 2.2.16, 2.3 before 2.3.13, and 2.4 before 2.4.3. It can lead to a situation with an attacker-controlled HTTP Host header, because a mismatch between Host and authority is mishandled. (CVE-2021-39242)

- An issue was discovered in HAProxy 2.2 before 2.2.16, 2.3 before 2.3.13, and 2.4 before 2.4.3. It does not ensure that the scheme and path portions of a URI have the expected characters. For example, the authority field (as observed on a target HTTP/2 server) might differ from what the routing rules were intended to achieve. (CVE-2021-39240)

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.
