high Tenable Cloud Security Plugin ID 450689

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Envoy is a cloud-native high-performance edge/middle/service proxy. Envoy’s HTTP/2 codec may leak a header
 map and bookkeeping structures upon receiving `RST_STREAM` immediately followed by the `GOAWAY` frames
 from an upstream server. In nghttp2, cleanup of pending requests due to receipt of the `GOAWAY` frame
 skips de-allocation of the bookkeeping structure and pending compressed header. The error return [code
 path] is taken if connection is already marked for not sending more requests due to `GOAWAY` frame. The
 clean-up code is right after the return statement, causing memory leak. Denial of service through memory
 exhaustion. This vulnerability was patched in versions(s) 1.26.3, 1.25.8, 1.24.9, 1.23.11.
 (CVE-2023-35945)
