Azure Linux 3.0 Security Update: cmake / nghttp2 / nodejs / nodejs18 (CVE-2023-35945)

high Nessus Plugin ID 233155

Synopsis

The remote Azure Linux host is missing one or more security updates.

Description

The version of cmake / nghttp2 / nodejs / nodejs18 installed on the remote Azure Linux 3.0 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the CVE-2023-35945 advisory.

 - 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)
