Title:	Huawei EulerOS: Security Advisory for samba (EulerOS-SA-2022-1094)
Summary:	The remote host is missing an update for the Huawei EulerOS 'samba' package(s) announced via the EulerOS-SA-2022-1094 advisory.
Description:	Summary: The remote host is missing an update for the Huawei EulerOS 'samba' package(s) announced via the EulerOS-SA-2022-1094 advisory. Vulnerability Insight: A flaw was found in samba. The Samba smbd file server must map Windows group identities (SIDs) into unix group ids (gids). The code that performs this had a flaw that could allow it to read data beyond the end of the array in the case where a negative cache entry had been added to the mapping cache. This could cause the calling code to return those values into the process token that stores the group membership for a user. The highest threat from this vulnerability is to data confidentiality and integrity.(CVE-2021-20254) Affected Software/OS: 'samba' package(s) on Huawei EulerOS Virtualization for ARM 64 3.0.6.0. Solution: Please install the updated package(s). CVSS Score: 4.9 CVSS Vector: AV:N/AC:M/Au:S/C:P/I:P/A:N
