First published: Tue Feb 18 2014(Updated: )
Vasily Kulikov reported a flaw in the Linux kernel's implementation of ptrace. An unprivileged local user could exploit this flaw to obtain sensitive information from kernel memory. (CVE-2013-2929) A flaw in the handling of memory regions of the kernel virtual machine (KVM) subsystem was discovered. A local user with the ability to assign a device could exploit this flaw to cause a denial of service (memory consumption). (CVE-2013-4592) Nico Golde and Fabian Yamaguchi reported a flaw in the Linux kernel's debugfs filesystem. An administrative local user could exploit this flaw to cause a denial of service (OOPS). (CVE-2013-6378) Nico Golde and Fabian Yamaguchi reported a flaw in the driver for Adaptec AACRAID scsi raid devices in the Linux kernel.
