- CVE-2020-8659
CNCF Envoy through 1.13.0 may consume excessive amounts of memory when proxying HTTP/1.1 requests or responses with many small (i.e. 1 byte) chunks.
Upstream, EPSS 1.89% - CVE-2020-8660
CNCF Envoy through 1.13.0 TLS inspector bypass. TLS inspector could have been bypassed (not recognized as a TLS client) by a client using only TLS 1.3. Because TLS extensions (SNI, ALPN) were not inspected, those connections might have been matched to a wrong filter chain, possibly bypassing some security restrictions in the process.
Upstream, EPSS 0.61% - CVE-2020-8661
CNCF Envoy through 1.13.0 may consume excessive amounts of memory when responding internally to pipelined requests.
Upstream, EPSS 1.87% - CVE-2020-8664
CNCF Envoy through 1.13.0 has incorrect Access Control when using SDS with Combined Validation Context. Using the same secret (e.g. trusted CA) across many resources together with the combined validation context could lead to the “static” part of the validation context to be not applied, even though it was visible in the active config dump.
