CVE-2017-9800 (opens in a new tab)How to fix?
Upgrade RHEL:7 subversion-ruby to version 0:1.7.14-11.el7_4 or higher.
This issue was patched in RHSA-2017:2480.
NVD Description
Note: Versions mentioned in the description apply only to the upstream subversion-ruby package and not the subversion-ruby package as distributed by RHEL.
See How to fix? for RHEL:7 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://.
