  • the Xen implementation did not prevent applications running in a para-virtualized guest from modifying CR4 TSC. This could cause a local denial of service.
    (CVE-2007-5907, Important)

    • Tavis Ormandy reported missing boundary checks in the Virtual Dynamic Shared Objects (vDSO) implementation.
      This could allow a local unprivileged user to cause a denial of service or escalate privileges.
      (CVE-2008-3527, Important)

    • the do_truncate() and generic_file_splice_write() functions did not clear the setuid and setgid bits. This could allow a local unprivileged user to obtain access to privileged information. (CVE-2008-4210, CVE-2008-3833, Important)

    • a flaw was found in the Linux kernel splice implementation. This could cause a local denial of service when there is a certain failure in the add_to_page_cache_lru() function. (CVE-2008-4302, Important)

    • a flaw was found in the Linux kernel when running on AMD64 systems. During a context switch, EFLAGS were being neither saved nor restored. This could allow a local unprivileged user to cause a denial of service.
      (CVE-2006-5755, Low)

    • a flaw was found in the Linux kernel virtual memory implementation. This could allow a local unprivileged user to cause a denial of service. (CVE-2008-2372, Low)

    • an integer overflow was discovered in the Linux kernel Datagram Congestion Control Protocol (DCCP) implementation. This could allow a remote attacker to cause a denial of service. By default, remote DCCP is blocked by SELinux. (CVE-2008-3276, Low)

In addition, these updated packages fix the following bugs :

  • random32() seeding has been improved.

  • in a multi-core environment, a race between the QP async event-handler and the destro_qp() function could occur.
    This led to unpredictable results during invalid memory access, which could lead to a kernel crash.

  • a format string was omitted in the call to the request_module() function.

  • a stack overflow caused by an infinite recursion bug in the binfmt_misc kernel module was corrected.

  • the ata_scsi_rbuf_get() and ata_scsi_rbuf_put() functions now check for scatterlist usage before calling kmap_atomic().

  • a sentinel NUL byte was added to the device_write() function to ensure that lspace.name is NUL-terminated.

  • in the character device driver, a range_is_allowed() check was added to the read_mem() and write_mem() functions. It was possible for an illegitimate application to bypass these checks, and access /dev/mem beyond the 1M limit by calling mmap_mem() instead. Also, the parameters of range_is_allowed() were changed to cleanly handle greater than 32-bits of physical address on 32-bit architectures.

  • some of the newer Nehalem-based systems declare their CPU DSDT entries as type ‘Alias’. During boot, this caused an ‘Error attaching device data’ message to be logged.

  • the evtchn event channel device lacked locks and memory barriers. This has led to xenstore becoming unresponsive on the Itanium® architecture.

  • sending of gratuitous ARP packets in the Xen frontend network driver is now delayed until the backend signals that its carrier status has been processed by the stack.

  • on forcedeth devices, whenever setting ethtool parameters for link speed, the device could stop receiving interrupts.

  • the CIFS ‘forcedirectio’ option did not allow text to be appended to files.

  • the gettimeofday() function returned a backwards time on Intel® 64.

  • residual-count corrections during UNDERRUN handling were added to the qla2xxx driver.

  • the fix for a small quirk was removed for certain Adaptec controllers for which it caused problems.

  • the ‘xm trigger init’ command caused a domain panic if a userland application was running on a guest on the Intel® 64 architecture.
