An update for grub2 is now available for openEuler-20.03-LTS-SP1,openEuler-20.03-LTS-SP2 and openEuler-20.03-LTS-SP3 Security Advisory openeuler-security@openeuler.org openEuler security committee openEuler-SA-2022-1597 Final 1.0 1.0 2022-03-26 Initial 2022-03-26 2022-03-26 openEuler SA Tool V1.0 2022-03-26 grub2 security update An update for grub2 is now available for openEuler-20.03-LTS-SP1,openEuler-20.03-LTS-SP2 and openEuler-20.03-LTS-SP3. GNU GRUB is a Multiboot boot loader. It was derived from GRUB, the GRand Unified Bootloader, which was originally designed and implemented by Erich Stefan Boleyn. Security Fix(es): A flaw in grub2 was found where its configuration file, known as grub.cfg, is being created with the wrong permission set allowing non privileged users to read its content. This represents a low severity confidentiality issue, as those users can eventually read any encrypted passwords present in grub.cfg. This flaw affects grub2 2.06 and previous versions. This issue has been fixed in grub upstream but no version with the fix is currently released.(CVE-2021-3981) An update for grub2 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 low. 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.
