tag_insight = "Security:
* An integer overflow flaw, leading to a heap-based buffer overflow, was
found in the way the Intel i915 driver in the Linux kernel handled the
allocation of the buffer used for relocation copies. A local user with
console access could use this flaw to cause a denial of service or escalate
their privileges. (CVE-2013-0913, Important)
* A buffer overflow flaw was found in the way UTF-8 characters were
converted to UTF-16 in the utf8s_to_utf16s() function of the Linux kernel's
FAT file system implementation. A local user able to mount a FAT file
system with the "utf8=1" option could use this flaw to crash the
system or, potentially, to escalate their privileges. (CVE-2013-1773,
Important)
* A flaw was found in the way KVM handled guest time updates when the
buffer the guest registered by writing to the MSR_KVM_SYSTEM_TIME machine
state register (MSR) crossed a page boundary. A privileged guest user could
use this flaw to crash the host or, potentially, escalate their privileges,
allowing them to execute arbitrary code at the host kernel level.
(CVE-2013-1796, Important)
* A potential use-after-free flaw was found in the way KVM handled guest
time updates when the GPA (guest physical address) the guest registered by
writing to the MSR_KVM_SYSTEM_TIME machine state register (MSR) fell into a
movable or removable memory region of the hosting user-space process (by
default, QEMU-KVM) on the host. If that memory region is deregistered from
KVM using KVM_SET_USER_MEMORY_REGION and the allocated virtual memory
reused, a privileged guest user could potentially use this flaw to
escalate their privileges on the host. (CVE-2013-1797, Important)
* A flaw was found in the way KVM emulated IOAPIC (I/O Advanced
Programmable Interrupt Controller). A missing validation check in the
ioapic_read_indirect() function could allow a privileged guest user to
crash the host, or read a substantial portion of host kernel memory.
(CVE-2013-1798, Important)
* A race condition in install_user_keyrings(), leading to a NULL pointer
dereference, was found in the key management facility. A local,
unprivileged user could use this flaw to cause a denial of service.
(CVE-2013-1792, Moderate)
* A NULL pointer dereference in the XFRM implementation could allow a local
user who has the CAP_NET_ADMIN capability to cause a denial of service.
(CVE-2013-1826, Moderate)
* A NULL pointer dereference in the Datagram Congestion Control Protocol
(DCCP) implementation could allow a local user to cause a denial of
service. (CVE ...
