kernel: a bug in ip_frag_reasm() can cause a crash in ip_do_fragment()

A security flaw was found in the ipfragreasm function in net/ipv4/ipfragment.c in the Linux kernel which can cause a later system crash in ipdofragment. With certain non-default, but non-rare, configuration of a victim host, an attacker can trigger this crash remotely, thus leading to a remote...
