Ubuntu Security Notice (C) 2013 Canonical, Inc. / NASL script (C) 2013 Tenable Network Security, Inc.
The remote Ubuntu host is missing one or more security-related patches.
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.
A flaw was discovered in the Linux kernels handling of memory ranges
with PROT_NONE when transparent hugepages are in use. An unprivileged
local user could exploit this flaw to cause a denial of service (crash
the system). (CVE-2013-0309)
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).
Update the affected packages.
