Language:

Synopsis

The remote Debian host is missing a security update.

Description

One security issue has been discovered in subversion :

CVE-2020-17525 :

Subversion's mod_authz_svn module will crash if the server is using in-repository authz rules with the AuthzSVNReposRelativeAccessFile option and a client sends a request for a non-existing repository URL.
This can lead to disruption for users of the service.

For Debian 9 stretch, this problem has been fixed in version 1.9.5-1+deb9u6.

We recommend that you upgrade your subversion packages.
