SCA: security update for github.com/envoyproxy/envoy (GHSA-mp85-7mrq-r866)

medium Tenable Cloud Security Plugin ID 436267

Description

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

 - Envoy is a high-performance edge/middle/service proxy. In 1.33.12, 1.34.10, 1.35.6, 1.36.2, and earlier,
 Envoy crashes when JWT authentication is configured with the remote JWKS fetching, allow_missing_or_failed
 is enabled, multiple JWT tokens are present in the request headers and the JWKS fetch fails. This is
 caused by a re-entry bug in the JwksFetcherImpl. When the first token's JWKS fetch fails, onJwksError()
 callback triggers processing of the second token, which calls fetch() again on the same fetcher object.
 The original callback's reset() then clears the second fetch's state (receiver_ and request_) which causes
 a crash when the async HTTP response arrives. (CVE-2025-64527)
