Description

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).

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.
