CVE-2017-8807 varnish: Data leak - ‘-sfile’ Stevedore transient objects
A wrong if statement in the varnishd source code means that synthetic objects in stevedores which over-allocate, may leak up to page size of data from a malloc(3) memory allocation.
In a unpredictable percentage of the cases where this condition arises, a segmentation fault will happen instead.
All the following conditions are required to trigger the problem:
A -sfile or -spersistent stevedore must be configured
A synthetic object must be created in vcl_backend_error{}
The synthetic object ends up in the file or persistent stevedore.
For the third condition can arise in two different ways:
The stevedore named Transient is configured as -sfile or -spersistent (The default is -smalloc)
The default stevedore is -sfi
