RHSA-2013:0744: kernel security and bug fix update (Important)  

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-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 of service. (CVE-2013-1774, Low)
Red Hat would like to thank Andrew Honig of Google for reporting CVE-2013-1796, CVE-2013-1797, and CVE-2013-1798. CVE-2013-1792 was discovered by Mateusz Guzik of Red Hat EMEA GSS SEG Team.

Quick Help

Unknown Tests
There is a hardcoded maximum limit for number of tests displayed for a definition. For a small number of oval definitions, about ~1% of all, hundreds of test have been defined. This causes the pages to grow in size, exceed even 1mb, and they are unsuitable for display in a web page. So they are not displayed.Please refer to the xml definition files if you really want to view them.
evr_string datatype
Represents epoch, version, and release number as a single version string
