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 ProgrammableInterrupt 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-2013-1827, Moderate) * Information leak flaws in the XFRM implementation could allow a local user who has the CAP_NET_ADMIN capability to leak kernel stack memory to user-space. (CVE-2012-6537, Low) * Two information leak flaws in the Asynchronous Transfer Mode (ATM) subsystem could allow a local, unprivileged user to leak kernel stack memory to user-space. (CVE-2012-6546, Low) * An information leak was found in the TUN/TAP device driver in the networking implementation. A local user with access to a TUN/TAP virtual interface could use this flaw to leak kernel stack memory to user-space. (CVE-2012-6547, Low) * An information leak in the Bluetooth implementation could allow a local user who has the CAP_NET_ADMIN capability to leak kernel stack memory to user-space. (CVE-2013-0349, Low) * A use-after-free flaw was found in the tmpfs implementation. A local user able to mount and unmount a tmpfs file system could use this flaw to cause a denial of service or, potentially, escalate their privileges. (CVE-2013-1767, Low) * A NULL pointer dereference was found in the Linux kernel's USB Inside Out Edgeport Serial Driver implementation. An attacker with physical access to a system could use this flaw to cause a denial ofservice.
