Multiple vulnerabilities in versions prior to 2.6.13.2 allow local users to cause a DoS (oops from null dereference) via fput in a 32bit ioctl on 64-bit x86 systems or sockfd_put in the 32-bit routing_ioctl function on 64-bit systems (CVE-2005-3044). Note that this was previously partially corrected in MDKSA-2005:235.

By performing particular socket operations, a local attacker could exploit this to crash the kernel. This flaw only affects Ubuntu 5.10. (CVE-2005-3359) David Howells noticed a race condition in the add_key(), request_key() and keyctl() functions. By modifying the length of string arguments after the kernel determined their length, but before the kernel copied them into kernel memory, a local attacker could either crash the kernel or read random parts of kernel memory (which could potentially contain sensitive data). (CVE-2006-0457) An information disclosure vulnerability was discovered in the ftruncate() function for the XFS file system. Under certain conditions, this function could expose random unallocated blocks. A local user could potentially exploit this to recover sensitive data from previously deleted files. (CVE-2006-0554) A local Denial of Service vulnerability was found in the NFS client module. By opening a file on an NFS share with O_DIRECT and performing some special operations on it, a local attacker could trigger a kernel crash. (CVE-2006-0555) The ELF binary loader did not sufficiently verify some addresses in the ELF headers. By attempting to execute a specially crafted program, a local attacker could exploit this to trigger a recursive loop of kernel errors, which finally ended in a kernel crash. This only affects the amd64 architecture on Intel processors (EMT64).
