(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 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.
