value:
" - 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."
