According to the version of the subversion packages installed, the EulerOS installation on the remote host is affected by the following vulnerability :

  • In Apache Subversion versions up to and including 1.9.10, 1.10.4, 1.12.0, Subversion’s svnserve server process may exit when a well-formed read-only request produces a particular answer. This can lead to disruption for users of the server.(CVE-2018-11782)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
