Synopsis: ELSA-2013-2511 can now be patched using Ksplice
CVEs: CVE-2013-0268
Users with Oracle Linux Premier Support can now use Ksplice to patch
against the latest Oracle Security Advisory, ELSA-2013-2511.
INSTALLING THE UPDATES
We recommend that all users of Ksplice Uptrack on EL 5 install these
updates.
On systems that have "autoinstall = yes" in /etc/uptrack/uptrack.conf,
these updates will be installed automatically and you do not need to
take any action.
Alternatively, you can install these updates by running:
# /usr/sbin/uptrack-upgrade -y
DESCRIPTION
* Kernel crash in floppy module initialization and exit.
Incorrect handling of errors and incorrect reference counting could
result in a kernel crash when inserting or removing the floppy module.
* Stale data exposure in XFS with custom extent sizes.
A directory on an xfs filesystem with a custom extent size could allow
stale data to be leaked when writing files with holes in them.
* Kernel crash in paravirtualization lazy mode during interrupts.
A race condition between different paravirtualized lazy modes during
interrupt handling could result in a BUG_ON() and kernel crash.
* CVE-2013-0268: /dev/cpu/*/msr local privilege escalation.
Access to /dev/cpu/*/msr was protected only using filesystem
checks. A local uid 0 (root) user with all capabilities dropped
could use this flaw to execute arbitrary code in kernel mode.
SUPPORT
Ksplice support is available at ksplice-support_ww at oracle.com.
