Posted Jun 14, 2013

Authored by Ubuntu | Site security.ubuntu.com

Ubuntu Security Notice 1876-1 - Andrew Honig reported a flaw in the way KVM (Kernel-based Virtual Machine) emulated the IOAPIC. A privileged guest user could exploit this flaw to read host memory or cause a denial of service (crash the host). An information leak was discovered in the Linux kernel's rcvmsg path for ATM (Asynchronous Transfer Mode). A local user could exploit this flaw to examine potentially sensitive information from the kernel's stack memory. Various other issues were also addressed.
