		<Note Title="Synopsis" Type="General" Ordinal="1" xml:lang="en">rust security update</Note>
		<Note Title="Summary" Type="General" Ordinal="2" xml:lang="en">An update for rust is now available for openEuler-20.03-LTS-SP1 and openEuler-20.03-LTS-SP2.</Note>
		<Note Title="Description" Type="General" Ordinal="3" xml:lang="en">Rust is a systems programming language that runs blazingly fast, prevents segfaults, and guarantees thread safety.

Security Fix(es):

library/std/src/net/parser.rs in Rust before 1.53.0 does not properly consider extraneous zero characters at the beginning of an IP address string, which (in some situations) allows attackers to bypass access control that is based on IP addresses, because of unexpected octal interpretation.(CVE-2021-29922)</Note>
		<Note Title="Topic" Type="General" Ordinal="4" xml:lang="en">An update for rust is now available for openEuler-20.03-LTS-SP1 and openEuler-20.03-LTS-SP2.

openEuler Security has rated this update as having a security impact of critical. 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>
