CVE-2017-9800 (opens in a new tab)How to fix?
Upgrade Debian:unstable subversion to version 1.9.7-1 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream subversion package and not the subversion package as distributed by Debian.
See How to fix? for Debian:unstable relevant fixed versions and status.
A maliciously constructed svn+ssh:// URL would cause Subversion clients before 1.8.19, 1.9.x before 1.9.7, and 1.10.0.x through 1.10.0-alpha3 to run an arbitrary shell command. Such a URL could be generated by a malicious server, by a malicious user committing to a honest server (to attack another user of that server's repositories), or by a proxy server. The vulnerability affects all clients, including those that use file://, http://, and plain (untunneled) svn://.
