Synopsis: ELSA-2016-0176 can now be patched using Ksplice
CVEs: CVE-2015-7547

Users with Oracle Linux Premier Support can now use Ksplice to patch
against the latest Oracle Security Advisory, ELSA-2016-0176.

INSTALLING THE UPDATES

We recommend that all users of Ksplice on OL 7 install these updates.

You can install these updates by running:

# ksplice -y user upgrade

32-bit applications should be restarted after upgrading the on-disk
glibc RPMs and statically linked applications using
glibc should be rebuilt to include these fixes.


DESCRIPTION

* CVE-2015-7547: Remote code execution in glibc DNS resolver.

A stack-based buffer overflow in the glibc libresolv library could be
triggered by a remote attacker with specially crafted DNS responses.
This could result in an application crash, or potentially allow
execution of arbitrary code with permissions of the user running the
library.

SUPPORT

Ksplice support is available at ksplice-support_ww at oracle.com.
