"It was discovered that the Auerswald usb driver incorrectly handled
lengths of the USB string descriptors. A local attacker with physical
access could insert a specially crafted USB device and gain root
privileges. (CVE-2009-4067)

It was discovered that the Stream Control Transmission Protocol (SCTP)
implementation incorrectly calculated lengths. If the
net.sctp.addip_enable variable was turned on, a remote attacker could
send specially crafted traffic to crash the system. (CVE-2011-1573)

Vasiliy Kulikov discovered that taskstats did not enforce access
restrictions. A local attacker could exploit this to read certain
information, leading to a loss of privacy. (CVE-2011-2494)

Vasiliy Kulikov discovered that /proc/PID/io did not enforce access
restrictions. A local attacker could exploit this to read certain
information, leading to a loss of privacy. (CVE-2011-2495)

Dan Kaminsky discovered that the kernel incorrectly handled random
sequence number generation. An attacker could use this flaw to
possibly predict sequence numbers and inject packets. (CVE-2011-3188).

Note that Tenable Network Security has extracted the preceding
description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."
