INSTALLING THE UPDATES

We recommend that all users of Ksplice Uptrack on RHEL 5 install these
updates.

On systems that have "autoinstall = yes" in /etc/uptrack/uptrack.conf,

take any action.

Alternatively, you can install these updates by running:

# /usr/sbin/uptrack-upgrade -y


DESCRIPTION

* CVE-2013-6383: Missing capability check in AAC RAID compatibility ioctl.

A missing capability check in the AAC RAID compatibility ioctl allows local users
to gain elevated privileges.


* CVE-2013-2929: Incorrect permissions check in ptrace with dropped privileges.

The ptrace subsystem incorrectly checked the state of the fs.suid_dumpable
sysctl allowing a user to ptrace attach to a process if it had dropped
privileges to that user.


* CVE-2013-7263: Information leak in IPv4 and IPv6 socket recvmsg.

The IPv4, IPv6 and PhoNet recvmsg(2) ioctls do not initialise the length a network
address causing the contents of kernel memory to be disclosed to userspace under
certain circumstances.


* CVE-2013-4483: Denial-of-service in IPC subsystem when taking a reference count.

The ipc_rcu_putref function in ipc/util.c in the Linux kernel before 3.10
does not properly manage a reference count, which allows local users to
cause a denial of service (memory consumption or system crash) via a
crafted application.
