Ubuntu Security Notice 2050-1 - An information leak was discovered in the handling of ICMPv6 Router Advertisement (RA) messages in the Linux kernel's IPv6 network stack. A remote attacker could exploit this flaw to cause a denial of service (excessive retries and address-generation outage), and consequently obtain sensitive information. Dan Carpenter discovered an information leak in the HP Smart Array and Compaq SMART2 disk-array driver in the Linux kernel. A local user could exploit this flaw to obtain sensitive information from kernel memory. Various other issues were also addressed.
