USN-2178-1: Linux kernel vulnerabilities
First published: Sat Apr 26 2014(Updated: )
A flaw was discovered in the Kernel Virtual Machine (KVM) subsystem of the Linux kernel. A guest OS user could exploit this flaw to execute arbitrary code on the host OS. (CVE-2014-0049) Al Viro discovered an error in how CIFS in the Linux kernel handles uncached write operations. An unprivileged local user could exploit this flaw to cause a denial of service (system crash), obtain sensitive information from kernel memory, or possibly gain privileges. (CVE-2014-0069)
