Updates of 'apache-tomcat' packages of Photon OS have been released...

envoy: Response flooding for HTTP/1.1

A resource consumption vulnerability was found in the servicemesh-proxy in Envoy. An attacker could use pipelined requests to cause excessive amounts of memory to be used, possibly degrading or crashing the application...

envoy: Incorrect Access Control when using SDS with Combined Validation Context

An access control bypass vulnerability was found in envoy. When the same TLS secret is used across multiple resources, the client's data, such as the subject alternative name or hash, is not validated. This flaw could lead to a possible bypass of security restrictions...

envoy: Excessive CPU and/or memory usage when proxying HTTP/1.1

A resource consumption vulnerability was found in the servicemesh-proxy in Envoy. An attacker could send specially crafted small HTTP/1.1 packets that, when processed, could cause excessive amounts of memory to be used, possibly degrading or crashing the application...

envoy: TLS inspector bypassc

An access control bypass vulnerability was found in envoy. An attacker could send specially crafted packets over TLS v1.3 to possibly bypass security restrictions...

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...

CVE-2020-8661

CNCF Envoy through 1.13.0 may consume excessive amounts of memory when responding internally to pipelined requests...

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 thoug...
