---------- Forwarded message ---------- From: Alex McGeorge <alexm@immunityinc.com> Date: Mon, 18 Jun 2012 10:10:09 -0400 Subject: [Dailydave] CANVAS SYSRET Module To: dailydave@lists.immunityinc.com, canvas@lists.immunityinc.com Aloha lists, There has been a lot of talk about the SYSRET vulnerability [1] recently and even some pretty good write ups [2]. Of course the best discussion of this bug will undoubtedly come from Rafal at his BlackHat talk in Vegas [3]. For those of you who are eager to see an exploit for this vulnerability in action we've got you covered: http://partners.immunityinc.com/movies/SYSRET-v2.mov . The exploit has been available since Friday to CANVAS Early Updates (CEU) customers for their FreeBSD privilege escalation pleasure, courtesy of our Unix exploit development team. For CEU inquiries please email admin@immunityinc.com . We were chatting about this on Friday, do other people see FreeBSD in the enterprise on pen-tests? Outside of a few NAS solutions I've seen it employed in source control and for other important tasks (DNS, FTP). Now that Linux is so common place is FreeBSD considered exotic?
