Synopsis
The remote Red Hat CoreOS host is missing a security update for OpenShift Container Platform 4.12.56.Description
The remote Red Hat Enterprise Linux CoreOS 4 host has a package installed that is affected by a vulnerability as referenced in the RHSA-2024:1899 advisory.- An attacker may cause an HTTP/2 endpoint to read arbitrary amounts of header data by sending an excessive number of CONTINUATION frames. Maintaining HPACK state requires parsing and processing all HEADERS and CONTINUATION frames on a connection. When a request's headers exceed MaxHeaderBytes, no memory is allocated to store the excess headers, but they are still parsed. This permits an attacker to cause an HTTP/2 endpoint to read arbitrary amounts of header data, all associated with a request which is going to be rejected. These headers can include Huffman-encoded data which is significantly more expensive for the receiver to decode than for an attacker to send. The fix sets a limit on the amount of excess header frames we will process before closing a connection. (CVE-2023-45288)
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 RHCOS OpenShift Container Platform 4.12.56 package based on the guidance in RHSA-2024:1899.See Also
