		<Note Title="Synopsis" Type="General" Ordinal="1" xml:lang="en">grpc security update</Note>
		<Note Title="Summary" Type="General" Ordinal="2" xml:lang="en">An update for grpc is now available for openEuler-20.03-LTS-SP3,openEuler-22.03-LTS,openEuler-22.03-LTS-SP1 and openEuler-22.03-LTS-SP2.</Note>
		<Note Title="Description" Type="General" Ordinal="3" xml:lang="en">gRPC is a modern open source high performance RPC framework that can run in any environment. It can efficiently connect services in and across data centers with pluggable support for load balancing, tracing, health checking and authentication. It is also applicable in last mile of distributed computing to connect devices, mobile applications and browsers to backend services.

Security Fix(es):

Lack of error handling in the TCP server in Google&apos;s gRPC starting version 1.23 on posix-compatible platforms (ex. Linux) allows an attacker to cause a denial of service by initiating a significant number of connections with the server. Note that gRPC C++ Python, and Ruby are affected, but gRPC Java, and Go are NOT affected. (CVE-2023-4785)</Note>
		<Note Title="Topic" Type="General" Ordinal="4" xml:lang="en">An update for grpc is now available for openEuler-20.03-LTS-SP3,openEuler-22.03-LTS,openEuler-22.03-LTS-SP1 and openEuler-22.03-LTS-SP2.

openEuler Security has rated this update as having a security impact of high. A Common Vunlnerability Scoring System(CVSS)base score,which gives a detailed severity rating, is available for each vulnerability from the CVElink(s) in the References section.</Note>
