After a standard system upgrade you need to reboot your computer to effect the necessary changes.

Details follow:

Philipp Richter discovered that the AppleTalk protocol handler did not sufficiently verify the length of packets. By sending a crafted AppleTalk packet, a remote attacker could exploit this to crash the kernel. (CVE-2007-1357)

Gabriel Campana discovered that the do_ipv6_setsockopt() function did not sufficiently verifiy option values for IPV6_RTHDR. A local attacker could exploit this to trigger a kernel crash. (CVE-2007-1388)

A Denial of Service vulnerability was discovered in the nfnetlink_log() netfilter function. A remote attacker could exploit this to trigger a kernel crash. (CVE-2007-1496)

The connection tracking module for IPv6 did not properly handle the status field when reassembling fragmented packets, so that the final packet always had the 'established' state. A remote attacker could exploit this to bypass intended firewall rules. (CVE-2007-1497)

Masayuki Nakagawa discovered an error in the flowlabel handling of IPv6 network sockets. A local attacker could exploit this to crash the kernel. (CVE-2007-1592)

The do_dccp_getsockopt() function did not sufficiently verify the optlen argument. A local attacker could exploit this to read kernel memory (which might expose sensitive data) or cause a kernel crash. This only affects Ubuntu 7.04. (CVE-2007-1730)

The IPv4 and DECnet network protocol handlers incorrectly declared an array variable so that it became smaller than intended. By sending crafted packets over a netlink socket, a local attacker could exploit this to crash the kernel. (CVE-2007-2172)

The Linux Kernel contains a flaw that may allows a remote attacker to bypass certain netfilter rulesets. The issue is due to the 'nf_conntrack' function not copying 'nfctinfo' information resulting in IPv6 fragments are treated as established and could allow an attacker to bypass a ruleset that accepts established packets.
