The remote host is missing an update for the Huawei EulerOS
'openssh' package(s) announced via the EulerOS-SA-2020-2451 advisory.

Vulnerability Insight:
The scp client in OpenSSH 8.2 incorrectly sends duplicate responses to the server upon a utimes system call failure, which allows a malicious unprivileged user on the remote server to overwrite arbitrary files in the client's download directory by creating a crafted subdirectory anywhere on the remote server. The victim must use the command scp -rp to download a file hierarchy containing, anywhere inside, this crafted subdirectory. NOTE: the vendor points out that 'this attack can achieve no more than a hostile peer is already able to achieve within the scp protocol' and 'utimes does not fail under normal circumstances.'(CVE-2020-12062)

Affected Software/OS:
'openssh' package(s) on Huawei EulerOS Virtualization

Please install the updated package(s).
