FreeBSD : logstash -- Directory traversal vulnerability in the file output plugin (24bde04f-1a10-11e5-b43d-002590263bf5)

Synopsis :

The remote FreeBSD host is missing a security-related update.

Description :

Elastic reports :

An attacker could use the File output plugin with dynamic field
references in the path option to traverse paths outside of Logstash
directory. This technique could also be used to overwrite any files
which can be accessed with permissions associated with Logstash user.
This release sandboxes the paths which can be traversed using the
configuration. We have also disallowed use of dynamic field references
if the path options is pointing to an absolute path.

We have added this vulnerability to our CVE page and are working on
filling out the CVE. We would like to thank Colin Coghill for
reporting the issue and working with us on the resolution.
