DLA 1728-1: openssh security update
Package : openssh
Version : 1:6.7p1-5+deb8u8
CVE ID : CVE-2018-20685 CVE-2019-6109 CVE-2019-6111
Debian Bug : 793412 919101 923486


Multiple scp client vulnerabilities have been discovered in OpenSSH, the
premier connectivity tool for secure remote shell login and secure file
transfer.

CVE-2018-20685

In scp.c, the scp client allowed remote SSH servers to bypass
intended access restrictions via the filename of . or an empty
filename. The impact was modifying the permissions of the target
directory on the client side.

CVE-2019-6109

Due to missing character encoding in the progress display, a
malicious server (or Man-in-The-Middle attacker) was able to employ
crafted object names to manipulate the client output, e.g., by using
ANSI control codes to hide additional files being transferred. This
affected refresh_progress_meter() in progressmeter.c.

CVE-2019-6111

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 performed cursory validation of the object name
returned (only directory traversal attacks are prevented). A
malicious scp server (or Man-in-The-Middle attacker) was able to
overwrite arbitrary files in the scp client target directory. If
recursive operation (-r) was performed, the server was able to
manipulate subdirectories, as well (for example, to overwrite the
.ssh/authorized_keys file).

For Debian 8 "Jessie", these problems have been fixed in version
1:6.7p1-5+deb8u8.

We recommend that you upgrade your openssh packages.
