"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)

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 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)

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)

A flaw was discovered in the Edgeort USB serial converter driver when
the device is disconnected while it is in use. A local user could
exploit this flaw to cause a denial of service (system crash).
(CVE-2013-1774).

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).
