Linux Distros Unpatched Vulnerability : CVE-2019-6109

medium Nessus Plugin ID 222944

Language:

Synopsis

The Linux/Unix host has one or more packages installed with a vulnerability that the vendor indicates will not be patched.

Description

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

 - 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)

Note that Nessus relies on the presence of the package as reported by the vendor.

Solution

There is no known solution at this time.
