Synopsis: ELSA-2016-3635 can now be patched using Ksplice
Users with Oracle Linux Premier Support can now use Ksplice to patch
against the latest Oracle Linux Security Advisory, ELSA-2016-3635.
INSTALLING THE UPDATES
We recommend that all users of Ksplice Uptrack running UEKR4 4.1.12 on
OL6 and OL7 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
* Improve fix for Permission bypass when checking credentials for fs accesses.
An incorrect backport of the fix can result in a kernel error when
attempting to access another processes pagemep in proc.
* CVE-2016-1583: Privilege escalation in eCryptfs.
eCryptfs was incorrectly trying to use the mmap() file operation on lower
filesystem that may not support it. A local, unprivileged user could use
this flaw to cause a denial-of-service through recursive faults or
potentially escalate privileges.
Ksplice support is available at ksplice-support_ww at oracle.com.
