Security issue fixed :

CVE-2018-11803: Fixed a vulnerability that allowed malicious SVN clients to trigger a crash in mod_dav_svn by omitting the root path from a recursive directory listing request (bsc#1122842)

The installed version of Subversion Server is 1.10.x prior to 1.10.4 or 1.11.x prior to 1.11.1 and is, therefore, affected by a denial of service (DoS) vulnerability. A flaw exists in the implementation of mod_dav_svn due to failing to validate the root path of the directory listing provided by the client. An unauthenticated, remote attacker can exploit this issue, to cause the process to stop responding.

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

  - Subversion's mod_dav_svn Apache HTTPD module versions     1.11.0 and 1.10.0 to 1.10.3 will crash after     dereferencing an uninitialized pointer if the client     omits the root path in a recursive directory listing     operation.(CVE-2018-11803)
