[Ksplice][Virtuozzo 4.7 Updates] New updates available via Ksplice (2.6.32-042stab105.14)

[Samson Yeung]

Synopsis: 2.6.32-042stab105.14 can now be patched using Ksplice

Systems running Virtuozzo 4.7 or the OpenVZ RHEL 6 kernel can now use
Ksplice to patch against the latest Parallels Virtuozzo Containers 4.7
kernel security update, 2.6.32-042stab105.14.

INSTALLING THE UPDATES

We recommend that all users of Ksplice Uptrack on Virtuozzo 4.7 or
OpenVZ on RHEL 6 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

* NULL pointer dereference in bridge driver when setting MAC address.

Lack of checking for NULL when changing the mac address of a bridge
device could lead to a NULL pointer dereference. A local, privileged
user could use this flaw to cause a denial-of-service.


* Memory leak in proc filesystem when following symlinks.

A missing reference drop on error when following a symlink leads to a
memory leak. A local, unprivileged user could use this flaw to exhaust
the memory on the system and cause a denial-of-service.


* Memory leak when changing a network device namespace.

A missing reference drop when changing a network device namespace leads
to a memory leak. A local, privileged user could use this flaw to
exhaust the memory on the system and cause a denial-of-service.
