DESCRIPTION

* CVE-2013-6378: Denial-of-service in Marvell 8xxx Libertas WLAN driver.

Incorrect validation of user supplied data in the Marvell 8xxx Libertas
WLAN driver could allow a privileged user to trigger an invalid pointer
dereference and crash the system.


* CVE-2014-1874: Denial-of-service in SELinux on empty security context.

Incorrect input validation in the SELinux subsystem could lead to a NULL
pointer dereference. A local, privileged user could use this flaw to cause
a denial-of-service.


* CVE-2014-0203: Memory corruption on listing procfs symbolic links.

The symbolic link walking function didn't properly terminate it's return
value which could lead to excessive freeing of memory and consequent memory
corruption. A local, unprivileged user could use this flaw to crash the system.


* CVE-2014-1737, CVE-2014-1738: Local privilege escalation in floppy ioctl.

The floppy driver would leak internal memory addresses to userspace,
and would allow unprivileged userspace code to overwrite those
addresses, allowing for a local privilege escalation and gaining
of root.
