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,
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

* CVE-2012-2319: Buffer overflow mounting corrupted hfs filesystem.

A buffer overflow flaw was found in the hfsplus_bnode_read() function in
the HFS+ file system implementation.  This could lead to a denial of
service if a user browsed a specially-crafted HFS+ file system, for
example, by running "ls".


* CVE-2012-3412: Remote denial of service through TCP MSS option in SFC NIC.

A malicious remote user may trigger a denial-of-service in hosts using 
the SFC
NIC by reducing the size of the TCP MSS and causing the victim to run out
of resources while processing the packets.


* CVE-2012-3430: kernel information leak in RDS sockets.

Calling recvfrom() on an RDS socket could result in leaking the contents
of kernel stack memory to userspace.


* CVE-2012-3510: Denial of service in xacct_add_tsk.

An attacker could use a use-after-free in the xacct_add_tsk call to
cause a denial or service or information leak.
