| Description: | Summary:
The remote host is missing an update for the Huawei EulerOS 'openssh' package(s) announced via the EulerOS-SA-2019-2113 advisory.
Vulnerability Insight:
An issue was discovered in OpenSSH 7.9. Due to missing character encoding in the progress display, a malicious server (or Man-in-The-Middle attacker) can employ crafted object names to manipulate the client output, e.g., by using ANSI control codes to hide additional files being transferred. This affects refresh_progress_meter() in progressmeter.c.(CVE-2019-6109)
An issue was discovered in OpenSSH 7.9. Due to the scp implementation being derived from 1983 rcp, the server chooses which files/directories are sent to the client. However, the scp client only performs cursory validation of the object name returned (only directory traversal attacks are prevented). A malicious scp server (or Man-in-The-Middle attacker) can overwrite arbitrary files in the scp client target directory. If recursive operation (-r) is performed, the server can manipulate subdirectories as well (for example, to overwrite the .ssh/authorized_keys file).(CVE-2019-6111)
Affected Software/OS:
'openssh' package(s) on Huawei EulerOS V2.0SP8.
Solution:
Please install the updated package(s).
CVSS Score:
