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

Statement:

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.
