Security
There has been a fairly long list of kernel vulnerabilities over the last
few months, but few of them have received much serious attention (outside
of the security groups at numerous distributors, who have been duly issuing
patches as the issues come up). Here's a selection of recent problems.
| CVE | Fixed-in | Description |
|---|
| CAN-2005-2098 |
2.6.12.5
2.6.13 |
The session keyring code had an error path which could
fail to release the session management semaphore. As a result, any
local user could cause processes to hang. |
| CAN-2005-2099 |
2.6.12.5
2.6.13 |
A keyring which failed to instantiate correctly could
leave behind a NULL pointer which would subsequently be dereferenced by
the kernel, causing an oops. |
| CAN-2005-1761 |
2.6.12.1 |
A ptrace() bug on the ia64 architecture
enables local denial of service attacks. (Patch) |
| CAN-2005-1913 |
2.6.12.1 |
The subthread exec code did not properly reparent
timers, leading to an oops caused by a local user when signals are
delivered to the wrong thread. (Patch) |
| CAN-2005-2456 |
2.6.13 |
The XFRM policy parser had an array overflow, enabling
denial of service attacks by local users. (Patch) |
| CAN-2005-2457 |
2.6.13 |
Mounting a malicious compressed ISO filesystem could
lead to a kernel oops |
CAN-2005-2458
CAN-2005-2459 |
2.6.13 |
Two zlib vulnerabilities which can be used to oops the
kernel and create denial of service attacks. |
| CAN-2005-2490 |
2.6.13.1 |
A race condition with user space allows a local
attacker to change the contents of a message passed to the 32-bit
version of sendmsg() on 64-bit architectures. The result is a
locally exploitable buffer overflow. (Patch) |
| CAN-2005-2492 |
2.6.13.1 |
An unchecked user-space dereference in
sendmsg() can be exploited to oops the system. (Patch) |
| CAN-2005-2548 |
2.6.9 |
A hostile UDP packet could cause the 8021Q VLAN code
to oops, leading to remote denial of service attacks.
|
| CAN-2005-2555 |
2.6.13 |
The kernel failed to restrict kernel socket policy
loading to administrative users. (Patch)
|
| CAN-2005-3044 |
2.6.13.2 |
The 32-bit ioctl() handler on x86-64 was
missing an fput() call. This error could be exploited by a
local attacker to corrupt kernel data structures. (Patch) |
| CAN-2005-3053 |
2.6.13 |
The set_mempolicy() system call, used to tweak memory
behavior on NUMA systems, did not properly check the
policy argument. A local attacker could, by supplying a
negative value, could cause a kernel oops. (Patch) |
| CAN-2005-3106 |
2.6.11 |
A race condition between core dumps and exec() could
enable a local attacker to deadlock the system. (Patch) |
| CAN-2005-3107 |
2.6.11 |
Another local deadlock related to core dumps and
ptrace(). (Patch) |
| CAN-2005-3108 |
2.6.11 |
The right sort of I/O mapping could create information
leaks and kernel oopses on the x86-64 platform. It is hard to see
how this one could be exploited by an unprivileged user. (Patch) |
| CAN-2005-3109 |
2.6.11 |
A maliciously created HFS filesystem could oops the
kernel, if the system was configured to allow users to mount such
filesystems. (Patch) |
| CAN-2005-3110 |
2.6.12 |
A race condition in the netfilter ebtables module can
cause a kernel oops on SMP systems. (Patch). |
| CAN-2005-3119 |
2.6.13.4 |
A memory leak in the key request code could be used in
denial of service attacks. (Patch) |
| CAN-2005-3180 |
2.6.13.4 |
The orinoco driver can leak information onto the net. (Patch) |
| CAN-2005-3181 |
2.6.13.4 |
A memory leak in the audit code can be used for denial of service
attacks. (Patch) |
That is a long list of vulnerabilities. The fact that almost all of them
are "only" denial of service problems, and that only one of those is truly
remotely exploitable, is of limited consolation.
One may well wonder why the kernel is the source of so many security holes,
far more than any other package on the system. The complexity of the
kernel and the environment in which it runs, the fact that many
often-harmless bugs (such as memory leaks) turn into security issues for
the kernel, and the high level of auditing which is done on kernel code are
all part of the answer to that question. Unfortunately, the flow of
security issues in the kernel is unlikely to stop anytime soon.

It has been known for some time that high-resolution color printers added
codes to their output which would enable that output to be traced. The EFF
has now found and decoded those marks for a
number of popular printers. It turns out that the scheme used is fairly
simple - an unencrypted code which includes the printing time and the
serial number of the printer. See the EFF's printer
list to see if your printer encodes this information, and this page to
learn how to find and decode the markings.
The moral of the story is clear: if we do not control our devices, they
will not work in our interests. There are plenty of good reasons for
wanting to be able to print anonymously, and there is no doubt that this
sort of watermarking can be used for the suppression of dissent and the
shutting down of whistle-blowers. Thanks to the EFF, we can at least see
this particular bit of technological ratware. But, as the EFF says:
"Even worse, it shows how the government and private industry make
backroom deals to weaken our privacy by compromising everyday equipment
like printers. The logical next question is: what other deals have been or
are being made to ensure that our technology rats on us?"

Brief items
If you are running the Snort intrusion detection system along with the
"Back Orifice" preprocessor, you want to read the attached advisory (click
below). Back Orifice suffers from a buffer overflow which can be exploited
by any remote attacker who can get a UDP packet onto your network. The
hole can be closed by upgrading to snort 2.4.3, or by disabling Back
Orifice.

CVE #(s): | CAN-2005-1268
CAN-2005-2088
|
| Created: | July 25, 2005 |
Updated: | November 7, 2005 |
| Description: |
Watchfire reported a flaw that occurred when using the Apache server as an
HTTP proxy. A remote attacker could send an HTTP request with both a
"Transfer-Encoding: chunked" header and a "Content-Length" header. This
caused Apache to incorrectly handle and forward the body of the request in
a way that the receiving server processes it as a separate HTTP request.
This could allow the bypass of Web application firewall protection or lead
to cross-site scripting (XSS) attacks.
Marc Stern reported an off-by-one overflow in the mod_ssl CRL verification
callback. In order to exploit this issue the Apache server would need to
be configured to use a malicious certificate revocation list (CRL). |

libgd2: buffer overflows in PNG handling
| Package(s): | libgd2 |
CVE #(s): | CAN-2004-0990
CAN-2004-0941
|
| Created: | October 29, 2004 |
Updated: | June 28, 2006 |
| Description: |
Several buffer overflows have been discovered in libgd's PNG handling
functions.
If an attacker tricked a user into loading a malicious PNG image, they
could leverage this into executing arbitrary code in the context of
the user opening image. Most importantly, this library is commonly
used in PHP. One possible target would be a PHP driven photo website
that lets users upload images. Therefore this vulnerability might lead
to privilege escalation to a web server's privileges.
Multiple buffer overflows in the gd graphics library (libgd) 2.0.21 and
earlier may allow remote attackers to execute arbitrary code via malformed
image files that trigger the overflows due to improper calls to the
gdMalloc function. |

| Description: |
A Denial of Service vulnerability was discovered in the
sys_set_mempolicy() function. By calling the function with a negative
first argument, a local attacker could cause a kernel crash.
(CAN-2005-3053)
A race condition was discovered in the handling of shared memory
mappings with CLONE_VM. A local attacker could exploit this to cause a
deadlock (Denial of Service) by triggering a core dump while waiting
for a thread which had just performed an exec() system call.
(CAN-2005-3106)
A race condition was found in the handling of traced processes. When
one thread was tracing another thread that shared the same memory map,
a local attacker could trigger a deadlock (Denial of Service) by
forcing a core dump when the traced thread was in the TASK_TRACED
state. (CAN-2005-3107)
A vulnerability has been found in the "ioremap" module. By performing
certain IO mapping operations, a local attacker could either read
memory pages he has not normally access to (information leak) or cause
a kernel crash (Denial of Service). This only affects the amd64
platform. (CAN-2005-3108)
The HFS and HFS+ file system drivers did not properly verify that the
file system that was attempted to be mounted really was HFS/HFS+. On
machines which allow users to mount arbitrary removable devices as HFS
or HFS+ with an /etc/fstab entry, this could be exploited to trigger a
kernel crash. (CAN-2005-3109)
Steve Herrel discovered a race condition in the "ebtables" netfilter
module. A remote attacker could exploit this by sending specially
crafted packets that caused a value to be modified after it had

xine-lib: arbitrary code execution
| Package(s): | xine-lib |
CVE #(s): | CAN-2005-2967
|
| Created: | October 10, 2005 |
Updated: | October 12, 2005 |
| Description: |
Ulf Harnhammar discovered a format string vulnerability in the CDDB
module's cache file handling in the Xine library, which is used by packages
such as xine-ui, totem-xine, and gxine. By tricking an user into playing a
particular audio CD which has a specially-crafted CDDB entry, a remote
attacker could exploit this vulnerability to execute arbitrary code with
the privileges of the user running the application. Since CDDB servers
usually allow anybody to add and modify information, this exploit does not
even require a particular CDDB server to be selected. |
