Security Fix(es):

An out-of-bounds read flaw was found in the CLARRV, DLARRV, SLARRV, and ZLARRV functions in lapack through version 3.10.0, as also used in OpenBLAS before version 0.3.18. Specially crafted inputs passed to these functions could cause an application using lapack to crash or possibly disclose portions of its memory.(CVE-2021-4048)</Note>
		<Note Title="Topic" Type="General" Ordinal="4" xml:lang="en">An update for openblas 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 medium. 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>
