Synopsis: Important: kernel security and bug fix update
Issue date: 2008-05-07
CVE Names: CVE-2005-0504 CVE-2007-6282 CVE-2008-0007
CVE-2008-1375 CVE-2008-1615 CVE-2008-1669
These updated packages fix the following security issues:
* the absence of a protection mechanism when attempting to access a
critical section of code has been found in the Linux kernel open file
descriptors control mechanism, fcntl. This could allow a local
unprivileged user to simultaneously execute code, which would otherwise
be protected against parallel execution. As well, a race condition when
handling locks in the Linux kernel fcntl functionality, may have allowed
a process belonging to a local unprivileged user to gain re-ordered
access to the descriptor table.
(CVE-2008-1669, Important)
* on AMD64 architectures, the possibility of a kernel crash was
discovered by testing the Linux kernel process-trace ability. This could
allow a local unprivileged user to cause a denial of service (kernel crash).
(CVE-2008-1615, Important)
* the absence of a protection mechanism when attempting to access a
critical section of code, as well as a race condition, have been found
in the Linux kernel file system event notifier, dnotify. This could
allow a local unprivileged user to get inconsistent data, or to send
arbitrary signals to arbitrary system processes.
(CVE-2008-1375, Important)
* when accessing kernel memory locations, certain Linux kernel drivers
registering a fault handler did not perform required range checks. A
local unprivileged user could use this flaw to gain read or write access
to arbitrary kernel memory, or possibly cause a kernel crash.
(CVE-2008-0007, Important)
* the possibility of a kernel crash was found in the Linux kernel IPsec
protocol implementation, due to improper handling of fragmented ESP
packets. When an attacker controlling an intermediate router fragmented
these packets into very small pieces, it would cause a kernel crash on
the receiving node during packet reassembly.
(CVE-2007-6282, Important)
* a flaw in the MOXA serial driver could allow a local unprivileged user
to perform privileged operations, such as replacing firmware.
(CVE-2005-0504, Important)
As well, these updated packages fix the following bugs:
* multiple buffer overflows in the neofb driver have been resolved. It
was not possible for an unprivileged user to exploit these issues, and
as such, they have not been handled as security issues.
* a kernel panic, due to inconsistent detection of AGP aperture size,
has been resolved.
* a race condition in UNIX domain sockets may have caused "recv()" to
return zero. In clustered configurations, this may have caused
unexpected failovers.
* to prevent link storms, network link carrier events were delayed by up
to one second, causing unnecessary packet loss. Now, link carrier events
are scheduled immediately.
* a client-side race on blocking locks caused large time delays on NFS
file systems.
* in certain situations, the libATA sata_nv driver may have sent
commands with duplicate tags, which were rejected by SATA devices. This
may have caused infinite reboots.
* running the "service network restart" command may have caused
networking to fail.
* a bug in NFS caused cached information about directories to be stored
for too long, causing wrong attributes to be read.
* on systems with a large highmem/lowmem ratio, NFS write performance
may have been very slow when using small files.
* a bug, which caused network hangs when the system clock was wrapped
around zero, has been resolved.
