Description Laura Pardo 2019-01-23 15:49:45 UTC
Subversion 1.10.0 introduced server-side support for recursive directory listing operations. The implementation in mod_dav_svn failed to validate the root path of the directory listing provided by the client. If the client omits the root path, mod_dav_svn will deference an uninitialized pointer variable and crash the HTTPD worker process handling the request.

Created subversion tracking bugs for this issue:

Affects: fedora-all [bug 1671271]

Comment 5 Borja Tarraso 2019-03-01 14:06:04 UTC

This issue did not affect the versions of subversion as shipped with Red Hat Enterprise Linux 5, 6, and 7.

This issue does not affect any Ansible Tower supported versions: 3.2, 3.3 or 3.4, as their system jobs don't use mod_dav_svn module.
