This Metasploit module exploits a vulnerability in the rds_page_copy_user function in net/rds/page.c (RDS) in Linux kernel versions 2.6.30 to 2.6.36-rc8 to execute code as root (CVE-2010-3904). This module has been tested successfully on Fedora 13 (i686) kernel version 2.6.33.3-85.fc13.i686.PAE and Ubuntu 10.04 (x86_64) with kernel version 2.6.32-21-generic.

This update fixes the following security issue: A NULL pointer dereference flaw was found in the nf_ct_frag6_reasm() function in the Linux kernel's netfilter IPv6 connection tracking implementation. A remote attacker could use this flaw to send specially-crafted packets to a target system that is using IPv6 and also has the nf_conntrack_ipv6 kernel module loaded, causing it to crash.
baa3650c927f75b71009e6046fdee38dd97700186f1927162b03c07e62ab28f7Zero Day Initiative Advisory 12-129 - This vulnerability allows remote attackers to execute arbitrary code from the contact of kernelspace on vulnerable installations of Microsoft Windows. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the kernel's support for TrueType font parsing of compound glyphs. A sign extension error exists in win32k.sys when processing compound glyphs having a total number of contours above 0x7FFF. This can be exploited to corrupt kernel heap memory placed below the space allocated for the "flags" buffer and potentially execute arbitrary code in kernel space.
e75b08b74f32bfc501dc8a86f8d3c57d49f38b38038de8495feb68116308083eThe SCTP implementation used by FreeBSD ("reference implementation") is vulnerable to a remote NULL pointer dereference in kernel due to a logic bug. When parsing ASCONF chunks, an attempt is made to find an association by address. if the address found is INADDR_ANY, sctp_findassoc_by_vtag() is called and an attempt is made to find an association by vtag. Before searching for the vtag in a hash table, a pointer is set to NULL, with the intention of redefining it after finding the association. However, if the specified vtag is not found, the function returns and the ptr is never reinitialized, causing a kernel panic when the NULL pointer is later dereferenced by the SCTP_INP_DECR_REF macro when flow returns to sctp_process_control(). This is a proof of concept denial of service exploit.

A flaw was found in the way the pyGrub boot loader handled compressed kernel images. A privileged guest user in a para-virtualized guest could use this flaw to create a crafted kernel image that, when attempting to boot it, could result in an out-of-memory condition in the privileged domain.
