Right, there are backported patches against 2.6, but we're running 2.5 in contrib/ . This is all "I'm out of time right now", so if someone wants to do the ports work and/or the contrib work with the patches for this vuln then please do. I should be able to get to it in the next few days but I'm busy with family and employment. -adrian On 16 October 2017 at 10:19, Kevin Oberman <rkoberman@gmail.com> wrote: > On Mon, Oct 16, 2017 at 8:55 AM, Adrian Chadd <adrian.chadd@gmail.com> > wrote: >> >> hi, >> >> I got the patches a couple days ago.
