Ubuntu Update for Linux kernel vulnerabilities USN-416-1

Please Install the Updated Packages.

Mark Dowd discovered that the netfilter iptables module did not correcly handle fragmented IPv6 packets. By sending specially crafted packets, a remote attacker could exploit this to bypass firewall rules. This has has already been fixed for Ubuntu 6.10 in USN-395-1 this is the corresponding fix for Ubuntu 6.06.(CVE-2006-4572) Doug Chapman discovered an improper lock handling in the mincore() function. A local attacker could exploit this to cause an eternal hang in the kernel, rendering the machine unusable. (CVE-2006-4814) Al Viro reported that the ISDN PPP module did not initialize the reset state timer. By sending specially crafted ISDN packets, a remote attacker could exploit this to crash the kernel. (CVE-2006-5749) Various syscalls (like listxattr()) misinterpreted the return value of return_EIO() when encountering bad inodes. By issuing particular system calls on a malformed file system, a local attacker could exploit this to crash the kernel. (CVE-2006-5753) The task switching code did not save and restore EFLAGS of processes. By starting a specially crafted executable, a local attacker could exploit this to eventually crash many other running processes. This only affects the amd64 platform. (CVE-2006-5755) A race condition was found in the grow_buffers() function. By mounting a specially crafted ISO9660 or NTFS file system, a local attacker could exploit this to trigger an infinite loop in the kernel, rendering the machine unusable. (CVE-2006-5757) A buffer overread was found in the zlib_inflate() function. By tricking an user into mounting a specially crafted file system which uses zlib compression (such as cramfs), this could be exploited to crash the kernel. (CVE-2006-5823) The ext3 file system driver did not properly handle corrupted data structures. By mounting a specially crafted ext3 file system, a local attacker could exploit this to crash the kernel. (CVE-2006-6053) The ext2 file system driver did not properly handle corrupted data structures. By mounting a specially crafted ext2 file system, a local attacker could exploit this to crash the kernel. (CVE-2006-6054) The hfs file system driver did not properly handle corrupted data structures. By mounting a specially crafted hfs file system, a local attacker could exploit this to crash the kernel. This only affects systems which enable SELinux (Ubuntu disables SELinux by default). (CVE-2006-6056) Several vulnerabilities have been found in the GFS2 ...
