		<Note Title="Synopsis" Type="General" Ordinal="1" xml:lang="en">sudo security update</Note>
		<Note Title="Summary" Type="General" Ordinal="2" xml:lang="en">An update for sudo is now available for openEuler-20.03-LTS-SP1,openEuler-20.03-LTS-SP3,openEuler-22.03-LTS and openEuler-22.03-LTS-SP1.</Note>
		<Note Title="Description" Type="General" Ordinal="3" xml:lang="en">Sudo is a program designed to allow a sysadmin to give limited root privileges to users and log root activity.  The basic philosophy is to give as few privileges as possible but still allow people to get their work done.

Security Fix(es):

In Sudo before 1.9.12p2, the sudoedit (aka -e) feature mishandles extra arguments passed in the user-provided environment variables (SUDO_EDITOR, VISUAL, and EDITOR), allowing a local attacker to append arbitrary entries to the list of files to process. This can lead to privilege escalation. Affected versions are 1.8.0 through 1.9.12.p1. The problem exists because a user-specified editor may contain a &quot;--&quot; argument that defeats a protection mechanism, e.g., an EDITOR=&apos;vim -- /path/to/extra/file&apos; value.(CVE-2023-22809)</Note>
		<Note Title="Topic" Type="General" Ordinal="4" xml:lang="en">An update for sudo is now available for openEuler-20.03-LTS-SP1,openEuler-20.03-LTS-SP3,openEuler-22.03-LTS and openEuler-22.03-LTS-SP1.

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>
