Security
The Linux Security Module (LSM) framework is intended to allow security
modules to lock down a system by inserting checks whenever the kernel is
about to do something interesting. A security module hooks into those
check points and, for each operation, convinces itself that the
operation is allowed by the security policy currently in force. This
approach can work well if checks have been placed in all of the
relevant locations. A missing check could open a door allowing a
user-space process to do something which the site's policy would disallow.
Kostik Belousov recently noticed this sort
of problem in the 2.6 kernel: it seems that the readv() and
writev() system calls ran without calling the associated LSM
hook. The missing check means that a process which uses these calls
(rather than read() or write()) could perform file
I/O which was not subject to oversight by any security modules currently
loaded in the system. The practical effect of this vulnerability is
minimal: any security module worth its bits will have done its access
checks when the file is opened, so the ability to do unchecked reads and
writes should not open any gaping holes in the system.
The more important point is how easily this sort of opening can come
about. When the security modules patch was originally merged into the
kernel, it included checks on readv() and writev(). But
those system calls were later rewritten, and the LSM hooks fell by the
wayside. This change apparently happened
around 2.5.47, but it only came to light now.
Most kernel developers are only peripherally aware of the LSM system. Very
few of them know how to code an LSM call, and the rules for the insertion
of LSM checks are not particularly well documented. Code which is missing
an LSM call still appears to work just fine in normal testing and use. The
end result of all this is that it is trivially easy to omit an important
check, or to delete one by accident. Such mistakes can then go unnoticed
for years.
Anybody who depends on a Linux security module (such as SELinux) is
depending on comprehensive checking within the kernel. But, as has been
demonstrated here, it is hard to feel sure that the LSM checks are, indeed
comprehensive. There are many code paths through the kernel. When a
relatively simple system call can go unprotected for so long, how secure do
we feel about the more complex paths? It would seem that a thorough audit
is called for. An automated audit might even be better; it may well be
possible to adapt a tool like sparse to detect unchecked paths
through the kernel. Some work in this area could do a lot to increase the
level of trust which can be placed in LSM-based modules.

A Denial of Service vulnerability was detected in the stack segment
fault handler. A local attacker could exploit this by causing stack
fault exceptions under special circumstances (scheduling), which lead
to a kernel crash. (CAN-2005-1767)
Vasiliy Averin discovered a Denial of Service vulnerability in the
"tiocgdev" ioctl call and in the "routing_ioctl" function. By calling
fget() and fput() in special ways, a local attacker could exploit this
to destroy file descriptor structures and crash the kernel.

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. |

A number of vulnerabilities were discovered in OpenVPN that were fixed in
the 2.0.1 release:
A DoS attack against the server when run with "verb 0" and without
"tls-auth" when a client connection to the server fails certificate
verification, the OpenSSL error queue is not properly flushed. This could
result in another unrelated client instance on the server seeing the error
and responding to it, resulting in a disconnection of the unrelated client.
A DoS attack against the server by an authenticated client that sends a
packet which fails to decrypt on the server, the OpenSSL error queue was
not properly flushed. This could result in another unrelated client
instance on the server seeing the error and responding to it, resulting in
a disconnection of the unrelated client.
A DoS attack against the server by an authenticated client is possible in
"dev tap" ethernet bridging mode where a malicious client could
theoretically flood the server with packets appearing to come from hundreds
of thousands of different MAC addresses, resulting in the OpenVPN process
exhausting system virtual memory.
If two or more client machines tried to connect to the server at the same
time via TCP, using the same client certificate, a race condition could
crash the server if --duplicate-cn is not enabled on the server. |

Attached files are opened without any warnings directly from the user's cache directory. This can be exploited to execute arbitrary Javascript in context of "file://". Normally, filename extensions are determined by the "Content-Type" in Opera Mail. However, by appending an additional '.' to the end of a filename, an HTML file could be spoofed to be e.g. "image.jpg.". These two vulnerabilities combined may be exploited to conduct script insertion attacks if the user chooses to view an attachment named e.g. "image.jpg." e.g. resulting in disclosure of local files. These are fixed in Opera 8.50. |
