Linux Distros Unpatched Vulnerability : CVE-2019-9514

high Nessus Plugin ID 223045

Language:

Synopsis

The Linux/Unix host has one or more packages installed with a vulnerability that the vendor indicates will not be patched.

Description

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

- Some HTTP/2 implementations are vulnerable to a reset flood, potentially leading to a denial of service.
The attacker opens a number of streams and sends an invalid request over each stream that should solicit a stream of RST_STREAM frames from the peer. Depending on how the peer queues the RST_STREAM frames, this can consume excess memory, CPU, or both. (CVE-2019-9514)

Note that Nessus relies on the presence of the package as reported by the vendor.

Solution

There is no known solution at this time.
