Andrew Cooper of Citrix reported a Xen stack corruption in the Linux kernel. An unprivileged user in a 32bit PVOPS guest can cause the guest kernel to crash, or operate erroneously. (CVE-2013-0190)
A failure to validate input was discovered in the Linux kernel's Xen netback (network backend) driver. A user in a guest OS may exploit this flaw to cause a denial of service to the guest OS and other guest domains.
(CVE-2013-0216)
A memory leak was discovered in the Linux kernel's Xen netback (network backend) driver. A user in a guest OS could trigger this flaw to cause a denial of service on the system. (CVE-2013-0217)
A flaw was discovered in the Linux kernel Xen PCI backend driver. If a PCI device is assigned to the guest OS, the guest OS could exploit this flaw to cause a denial of service on the host. (CVE-2013-0231)
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)
Tommi Rantala discovered a flaw in the a flaw the Linux kernels handling of datagrams packets when the MSG_PEEK flag is specified. An unprivileged local user could exploit this flaw to cause a denial of service (system hang). (CVE-2013-0290)
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)
A flaw was discovered in the Extended Verification Module (EVM) of the Linux kernel. An unprivileged local user code exploit this flaw to cause a denial of service (system crash). (CVE-2013-0313)
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)
