INSTALLING THE UPDATES
We recommend that all users of Ksplice Uptrack on EL 5 install these
On systems that have "autoinstall = yes" in /etc/uptrack/uptrack.conf,

* CVE-2012-6638: Denial-of-service in TCP's SYN+FIN messages.
TCP's SYN+FIN messages had an issue where an attacker could cuase a
denial-of-service via a flood for SYN+FIN TCP packets.
* CVE-2013-2888: Kernel memory corruption flaw via oversize HID report id.
The Human Interface Device (HID) code is vulnerable to a memory
corruption flaw. An attacker could use this to crash the system
resulting in a denial-of-service or could elevate privileges.
* Panic in GFS2 filesystem locking code.
If a readpage operation attempted to take a lock that was already held
elsewhere, a kernel panic would occur.
* NULL pointer dereference in IUCV code.
In certain circumstances while establishing a connection, the Inter User
Communication Vehicle (IUCV) code would dereference a NULL pointer which
an attacker could use to cause a denial-of-service.
* Soft lockup as a result of a race in SUNRPC.
The functions rpc_wake_up_task and rpc_wake_up_status have a race where
threads running the functions could trigger a soft lockup which an
attacker could use to cause a denial-of-service.
