FreeBSD : FreeBSD -- L1 Terminal Fault (L1TF) Kernel Information Disclosure (2310b814-a652-11e8-805b-a4badb2f4699) (Foreshadow)
Medium Nessus Plugin ID 112069
SynopsisThe remote FreeBSD host is missing one or more security-related updates.
DescriptionOn certain Intel 64-bit x86 systems there is a period of time during terminal fault handling where the CPU may use speculative execution to try to load data. The CPU may speculatively access the level 1 data cache (L1D). Data which would otherwise be protected may then be determined by using side channel methods.
This issue affects bhyve on FreeBSD/amd64 systems. Impact : An attacker executing user code, or kernel code inside of a virtual machine, may be able to read secret data from the kernel or from another virtual machine.
SolutionUpdate the affected packages.
