"The remote Oracle Linux 8 host has packages installed that are affected by a vulnerability as referenced in the
ELSA-2024-1962 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)
