		<Note Title="Synopsis" Type="General" Ordinal="1" xml:lang="en">spark security update</Note>
		<Note Title="Summary" Type="General" Ordinal="2" xml:lang="en">An update for spark is now available for openEuler-20.03-LTS-SP1,openEuler-20.03-LTS-SP2 and openEuler-20.03-LTS-SP3.</Note>
		<Note Title="Description" Type="General" Ordinal="3" xml:lang="en">Apache Spark achieves high performance for both batch and streaming data, using a state-of-the-art DAG scheduler, a query optimizer, and a physical execution engine.

Security Fix(es):

Apache Spark supports end-to-end encryption of RPC connections via &quot;spark.authenticate&quot; and &quot;spark.network.crypto.enabled&quot;. In versions 3.1.2 and earlier, it uses a bespoke mutual authentication protocol that allows for full encryption key recovery. After an initial interactive attack, this would allow someone to decrypt plaintext traffic offline. Note that this does not affect security mechanisms controlled by &quot;spark.authenticate.enableSaslEncryption&quot;, &quot;spark.io.encryption.enabled&quot;, &quot;spark.ssl&quot;, &quot;spark.ui.strictTransportSecurity&quot;. Update to Apache Spark 3.1.3 or later(CVE-2021-38296)</Note>
		<Note Title="Topic" Type="General" Ordinal="4" xml:lang="en">An update for spark is now available for openEuler-20.03-LTS-SP1,openEuler-20.03-LTS-SP2 and openEuler-20.03-LTS-SP3.

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>
