| Description: | Summary:
The remote host is missing an update for the 'linux' package(s) announced via the USN-1767-1 advisory.
Vulnerability Insight:
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 buffer overflow was discovered in the Linux kernel's /dev/kmesg device. A
local user could exploit this flaw to cause a denial of service (system
crash). (CVE-2013-1772)
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)
