Description

Several local and remote vulnerabilities have been discovered in the
Linux kernel that may lead to a denial of service or the execution of
arbitrary code. The Common Vulnerabilities and Exposures project
identifies the following problems :

– CVE-2004-2302
A race condition in the sysfs filesystem allows local
users to read kernel memory and cause a denial of
service (crash).

– CVE-2005-0756
Alexander Nyberg discovered that the ptrace() system
call does not properly verify addresses on the amd64
architecture which can be exploited by a local attacker
to crash the kernel.

– CVE-2005-0757
A problem in the offset handling in the xattr file
system code for ext3 has been discovered that may allow
users on 64-bit systems that have access to an ext3
filesystem with extended attributes to cause the kernel
to crash.

– CVE-2005-1265
Chris Wright discovered that the mmap() function could
create illegal memory maps that could be exploited by a
local user to crash the kernel or potentially execute
arbitrary code.

– CVE-2005-1761
A vulnerability on the IA-64 architecture can lead local
attackers to overwrite kernel memory and crash the
kernel.

– CVE-2005-1762
A vulnerability has been discovered in the ptrace()
system call on the amd64 architecture that allows a
local attacker to cause the kernel to crash.

– CVE-2005-1763
A buffer overflow in the ptrace system call for 64-bit
architectures allows local users to write bytes into
arbitrary kernel memory.

– CVE-2005-1765
Zou Nan Hai has discovered that a local user could cause
the kernel to hang on the amd64 architecture after
invoking syscall() with specially crafted arguments.

– CVE-2005-1767
A vulnerability has been discovered in the stack segment
fault handler that could allow a local attacker to cause
a stack exception that will lead the kernel to crash
under certain circumstances.

– CVE-2005-2456
Balazs Scheidler discovered that a local attacker could
call setsockopt() with an invalid xfrm_user policy
message which would cause the kernel to write beyond the
boundaries of an array and crash.

– CVE-2005-2458
Vladimir Volovich discovered a bug in the zlib routines
which are also present in the Linux kernel and allows
remote attackers to crash the kernel.

– CVE-2005-2459
Another vulnerability has been discovered in the zlib
routines which are also present in the Linux kernel and
allows remote attackers to crash the kernel.

– CVE-2005-2548
Peter Sandstrom noticed that snmpwalk from a remote host
could cause a denial of service (kernel oops from null
dereference) via certain UDP packets that lead to a
function call with the wrong argument.

– CVE-2005-2801
Andreas Gruenbacher discovered a bug in the ext2 and
ext3 file systems. When data areas are to be shared
among two inodes not all information were compared for
equality, which could expose wrong ACLs for files.

– CVE-2005-2872
Chad Walstrom discovered that the ipt_recent kernel
module 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.

– CVE-2005-3105
The mprotect code on Itanium IA-64 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.

– CVE-2005-3106
A race condition in the thread management may allow
local users to cause a denial of service (deadlock) when
threads are sharing memory and waiting for a thread that
has just performed an exec.

– CVE-2005-3107
When one thread is tracing another thread that shares
the same memory map a local user could cause a denial of
service (deadlock) by forcing a core dump when the
traced thread is in the TASK_TRACED state.

– CVE-2005-3108
A bug in the ioremap() system call has been discovered
on the amd64 architecture that could allow local users
to cause a denial of service or an information leak when
performing a lookup of a non-existent memory page.

– CVE-2005-3109
The HFS and HFS+ (hfsplus) modules allow local attackers
to cause a denial of service (oops) by using hfsplus to
mount a filesystem that is not hfsplus.

– CVE-2005-3110
A race condition in the ebtables netfilter module on an
SMP system running under high load may allow remote
attackers to cause a denial of service (crash).

– CVE-2005-3271
Roland McGrath discovered that exec() does not properly
clear posix-timers in multi-threaded environments, which
results in a resource leak and could allow a large
number of multiple local users to cause a denial of
service by using more posix-timers than specified by the
quota for a single user.

– CVE-2005-3272
The kernel allows remote attackers to poison the bridge
forwarding table using frames that have already been
dropped by filtering, which can cause the bridge to
forward spoofed packets.

– CVE-2005-3273
The ioctl for the packet radio ROSE protocol does not
properly verify the arguments when setting a new router,
which allows attackers to trigger out-of-bounds errors.

– CVE-2005-3274
A race condition on SMP systems allows local users to
cause a denial of service (null dereference) by causing
a connection timer to expire while the connection table
is being flushed before the appropriate lock is
acquired.

– CVE-2005-3275
An error in the NAT code allows remote attackers to
cause a denial of service (memory corruption) by causing
two packets for the same protocol to be NATed at the
same time, which leads to memory corruption.

– CVE-2005-3276
A missing memory cleanup in the thread handling routines
before copying data into userspace allows a user process
to obtain sensitive information.

This update also contains a number of corrections for issues that
turned out to have no security implication afterwards.
