Description
While vbox makes sure it doesn't read in more than RCPS_MAX_NAMESERVERS nameserver lines when parsing /etc/resolv.conf, it doesn't enforce a similar check against RCPS_MAX_SEARCHLIST for search domains. When using a VPN, sometimes absurd numbers of search domains happen (glibc only supports 6) and vbox will just segfault.
I've made a fix (the resolv.conf parser helpfully compiles as a standalone program, which made locating the problematic chunk trivial) that I'll attach to this bug. Obligatory "patch is under the MIT license" because I did read the contributer guidelines.
