Description

Andrew Jones discovered a flaw with the xen_iret function in Linux kernel’s Xen virtualizeation. In the 32-bit Xen paravirt platform an unprivileged guest OS user could exploit this flaw to cause a denial of service (crash the system) or gain guest OS privilege. (CVE-2013-0228)

A flaw was reported in the permission checks done by the Linux kernel for /dev/cpu/*/msr. A local root user with all capabilities dropped could exploit this flaw to execute code with full root capabilities. (CVE-2013-0268)

A flaw was discovered in the Linux kernel’s vhost driver used to accelerate guest networking in KVM based virtual machines. A privileged guest user could exploit this flaw to crash the host system. (CVE-2013-0311)

An information leak was discovered in the Linux kernel’s Bluetooth stack when HIDP (Human Interface Device Protocol) support is enabled. A local unprivileged user could exploit this flaw to cause an information leak from the kernel. (CVE-2013-0349)

A flaw was discovered on the Linux kernel’s VFAT filesystem driver when a disk is mounted with the utf8 option (this is the default on Ubuntu). On a system where disks/images can be auto-mounted or a FAT filesystem is mounted an unprivileged user can exploit the flaw to gain root privileges. (CVE-2013-1773)
