In order to hopefully help kickstart the security update process, I've
drafted some DSA text for our sarge/2.6.8 kernels (attached). Thanks to
Micah, we have CAN IDs assigned for a number of things we just had
marked as security. I tried to map all of the patches to CANs, but
these are the ones remaining. Does anyone know if there is a CAN ID for
any of the following?

Multiple security vulnerabilities have been identified in the Linux kernel.
These vulnerabilities could allow an attacker to execute arbitrary code or
initiate a denial of service (DoS) attack.
CAN-2005-3105
The mprotect code (mprotect.c) in Linux 2.6 on Itanium IA64 Montecito
processors does not properly maintain cache coherency as required by
the architecture, which allows local users to cause a denial of service
and possibly corrupt data by modifying PTE protections.
CAN-2005-1763
Buffer overflow in ptrace in the Linux Kernel for 64-bit architectures
allows local users to write bytes into kernel memory.
CAN-2005-1762
The ptrace call in the Linux kernel 2.6.8.1 and 2.6.10 for the AMD64
platform allows local users to cause a denial of service (kernel crash)
via a "non-canonical" address.
CAN-2005-0756
ptrace 2.6.8.1 does not properly verify addresses on the amd64
platform, which allows local users to cause a denial of service (kernel
crash)
CAN-2005-3108
mm/ioremap.c in Linux 2.6 on 64-bit x86 systems allows local users to
cause a denial of service or an information leak via an iremap on a
certain memory map that causes the iounmap to perform a lookup of a
page that does not exist.
CAN-2005-3106
Race condition in Linux 2.6, when threads are sharing memory mapping
via CLONE_VM (such as linuxthreads and vfork), might allow local users
to cause a denial of service (deadlock) by triggering a core dump while
waiting for a thread that has just performed an exec.
CAN-2005-3107
fs/exec.c in Linux 2.6, when one thread is tracing another thread that
shares the same memory map, might allow local users to cause a denial
of service (deadlock) by forcing a core dump when the traced thread is
in the TASK_TRACED state.
CAN-2005-3109
The HFS and HFS+ (hfsplus) modules in Linux 2.6 allows attackers to
cause a denial of service (oops) by using hfsplus to mount a filesystem
that is not hfsplus.
CAN-2005-1265
The mmap function in the Linux Kernel 2.6.10 can be used to create
memory maps with a start address beyond the end address, which allows
local users to cause a denial of service (kernel crash).
CAN-2005-0757
The xattr file system code, as backported in Red Hat Enterprise Linux 3
on 64-bit systems, does not properly handle certain offsets, which
allows local users to cause a denial of service (system crash) via
certain actions on an ext3 file system with extended attributes
enabled.
CAN-2005-1765
syscall in the Linux kernel 2.6.8.1 and 2.6.10 for the AMD64 platform,
when running in 32-bit compatibility mode, allows local users to cause
a denial of service (kernel hang) via crafted arguments.
CAN-2005-1761
Linux kernel 2.6 and 2.4 on the IA64 architecture allows local users to
cause a denial of service (kernel crash) via ptrace and the
restore_sigcontext function.
CAN-2005-2548
vlan_dev.c in Linux kernel 2.6.8 allows remote attackers to cause a
denial of service (kernel oops from null dereference) via certain UDP
packets that lead to a function call with the wrong argument, as
demonstrated using snmpwalk on snmpd.
CAN-2004-2302
Race condition in the sysfs_read_file and sysfs_write_file functions in
Linux kernel before 2.6.10 allows local users to read kernel memory and
cause a denial of service (crash) via large offsets in sysfs files.
CAN-2005-1767
traps.c in the Linux kernel 2.6.x and 2.4.x executes stack segment
faults on an exception stack, which allows local users to cause a
denial of service (oops and stack fault exception).
CAN-2005-2458
inflate.c in the zlib routines in the Linux kernel before 2.6.12.5
allows remote attackers to cause a denial of service (kernel crash) via
a compressed file with "improper tables".
CAN-2005-2459
The huft_build function in inflate.c in the zlib routines in the Linux
kernel before 2.6.12.5 returns the wrong value, which allows remote
attackers to cause a denial of service (kernel crash) via a certain
compressed file that leads to a null pointer dereference, a different
vulnerability than CAN-2005-2458.
CAN-2005-2456
Array index overflow in the xfrm_sk_policy_insert function in
xfrm_user.c in Linux kernel 2.6 allows local users to cause a denial of
service (oops or deadlock) and possibly execute arbitrary code via a
p->dir value that is larger than XFRM_POLICY_OUT, which is used as an
index in the sock->sk_policy array.
CAN-2005-2872
The ipt_recent kernel module (ipt_recent.c) in Linux kernel before
2.6.12, when running on 64-bit processors such as AMD64, allows remote
attackers to cause a denial of service (kernel panic) via certain
attacks such as SSH brute force, which leads to memset calls using a
length based on the u_int32_t type, acting on an array of unsigned long
elements, a different vulnerability than CAN-2005-2873.
CAN-2005-2801
xattr.c in the ext2 and ext3 file system code for Linux kernel 2.6 does
not properly compare the name_index fields when sharing xattr blocks,
which could prevent default ACLs from being applied.
