[Oracle Ksplice]

Synopsis: FEDORA-2014-9959 can now be patched using Ksplice
CVEs: CVE-2014-5471 CVE-2014-5472

Systems running Fedora 20 can now use Ksplice to patch against the
latest Fedora kernel update, FEDORA-2014-9959.

INSTALLING THE UPDATES

We recommend that all users of Ksplice Uptrack on Fedora 20 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

* Denial-of-service when listing ACL on a NFS filesystem.

The error code of get_acl() in the NFS filesystem driver isn't properly
checked and could lead to an invalid pointer dereference and kernel
panic. A local, unprivileged user could use this flaw to cause a
denial-of-service.


* CVE-2014-5471, CVE-2014-5472: Privilege escalation in ISO filesystem implementation.

The parse_rock_ridge_inode_internal() function in the ISO filesystem driver
does not correctly check relocated directories when processing Rock Ridge
child link tags. An attacker with physical access to the system could use a
specially crafted ISO image to cause a denial of service or, potentially,
escalate their privileges.
