FreeBSD : xen-kernel -- arm: vgic-v2: GICD_SGIR is not properly emulated (785c86b1-27d6-11e5-a4a5-002590263bf5)
Medium Nessus Plugin ID 84704
SynopsisThe remote FreeBSD host is missing a security-related update.
DescriptionThe Xen Project reports :
When decoding a guest write to a specific register in the virtual interrupt controller Xen would treat an invalid value as a critical error and crash the host.
By writing an invalid value to the GICD.SGIR register a guest can crash the host, resulting in a Denial of Service attack.
SolutionUpdate the affected package.
