Re: [SECURITY] [DSA 2668-1] linux-2.6 security update

2013-05-14 Thread Jon Marshall
Saw this earlier, apparently there is a serious issue that affects all of the
kernels up to 3.8

Will do a security thing tomorrow, if I get a chance, but it has been a while
since we've had a look at it, my fault.

Will update once I've reviewed.
