Synopsis
The remote Red Hat CoreOS host is missing one or more security updates for OpenShift Container Platform 4.12.45.Description
The remote Red Hat Enterprise Linux CoreOS 4 host has a package installed that is affected by multiple vulnerabilities as referenced in the RHSA-2023:7610 advisory.- The HTTP/2 protocol allows a denial of service (server resource consumption) because request cancellation can reset many streams quickly, as exploited in the wild in August through October 2023. (CVE-2023-44487)
- Werkzeug is a comprehensive WSGI web application library. If an upload of a file that starts with CR or LF and then is followed by megabytes of data without these characters: all of these bytes are appended chunk by chunk into internal bytearray and lookup for boundary is performed on growing buffer. This allows an attacker to cause a denial of service by sending crafted multipart data to an endpoint that will parse it.
The amount of CPU time required can block worker processes from handling legitimate requests. This vulnerability has been patched in version 3.0.1. (CVE-2023-46136)
Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
