Important: kernel

Issue Overview: A flaw in the processing of received ICMP errors ICMP fragment needed and ICMP redirect in the Linux kernel functionality was found to allow the ability to quickly scan open UDP ports. This flaw allows an off-path remote user to effectively bypass the source port UDP randomization...

Important: kernel

Issue Overview: A denial of service flaw for virtual machine guests in the Linux kernel's Xen hypervisor subsystem was found in the way users call some interrupts with high frequency from one of the guests. A local user could use this flaw to starve the resources resulting in a denial of service...
