Some trusted computing security modules
IBM has been pushing the use of the "trusted platform module" chip found in
its laptops (and on other systems as well) for some time; see this report from OLS 2005 for a
summary of the benefits they see from trusted computing. Now IBM's
developers have posted a new set
of security modules which make use of the TPM to lock down a system.
The three modules are:
- The simple Linux integrity model, or SLIM. This module
associates two attributes with every process and every file: the
integrity level and the privacy level. The integrity levels are
"system," "user," and "untrusted." Any process may read or execute
any file with an equal or higher integrity level (subject to the usual
permissions). Read and execute access to lower-integrity files is
also allowed, but, as a result, the process will, itself, be demoted
to the lower level. Writing files with a higher integrity level is
not allowed. The integrity levels thus implement a form of simple,
automatic sandboxing; if a process touches untrusted resources, it
also loses trust and has a lowered ability to change things elsewhere
on the system. Network sockets, incidentally, are always considered
to have an "untrusted" integrity level.
The privacy level has four levels: public, user, user-sensitive, and
system-sensitive. Processes can read files of equal or lower
sensitivity. If, instead, a process reads a higher-sensitivity file,
its own sensitivity level is raised to match. Writing
lower-sensitivity files is not allowed. This "high watermark"
mechanism is intended to prevent the leakage of secret data to
less-trusted contexts.
- The SLIM module, like SELinux, depends on the extended attributes of
a file to make security decisions. But what if something is able to
change those attributes? The extended verification module
(EVM) is an attempt to keep that from happening. EVM creates its own
extended attribute on each file which is an HMAC hash of the file's
contents and attributes. If the file and the HMAC fail to match, EVM
will deny access to the file.
One might argue that EVM's hash is no less susceptible to tampering
than the other attributes on the file. The difference is that EVM
uses the hardware TPM module to sign the HMAC result. The TPM will
only perform this operation if it is satisfied that the proper "secure
boot" rituals have been followed, and that the integrity of the
running system has not been compromised. Since the TPM key is
specific to that particular chip, it is not possible to remove the
drive and forge HMACs on a different system. If the trusted boot
chain, starting with the BIOS, holds, there should be a high level of
assurance that the system's files and their attributes have not been
tampered with.
- The third module is the integrity measurement architecture.
LWN readers have seen IMA
before, so that discussion will not be repeated. In short, IMA is
a remote attestation feature which can provide a convincing proof that
a system is running (only) well-known, trusted versions of approved
software.
The IMA module was not well received when it was last posted. The
developers hope that the largest objections have been addressed, and that
the set of TPM-related modules as a whole can be considered, eventually,
for merging. Before reaching that point, however, these modules have
another obstacle to overcome: they rely on the ability to run multiple
Linux security modules in a "stacked" mode. Stacked security modules have
been a contentious issue for
some time, and that capability has never been merged. The developers claim
that the new modules will make the case for stacking, but that
conversation has yet to take place.

Discontinued SUSE Linux Distribution: 9.0
SUSE has a reminder that no security updates will be available for SUSE
Linux 9.0 after December 15, 2005. " As a consequence, the SUSE Linux
9.0 distribution directory on our ftp server ftp.suse.com has been moved
from /pub/suse/i386/9.0/ to the /pub/suse/discontinued/ directory tree

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. |

libnet-ssleay-perl: weakened cryptographic operations
| Package(s): | libnet-ssleay-perl |
CVE #(s): | CAN-2005-0106
|
| Created: | May 3, 2005 |
Updated: | January 27, 2006 |
| Description: |
Javier Fernandez-Sanguino Pena discovered that this library used the
file /tmp/entropy as a fallback entropy source if a proper source was
not set in the environment variable EGD_PATH. This can potentially
lead to weakened cryptographic operations if an attacker provides a
/tmp/entropy file with known content. |

libTIFF: buffer overflow
| Package(s): | libtiff |
CVE #(s): | CAN-2005-1544
|
| Created: | May 10, 2005 |
Updated: | February 17, 2006 |
| Description: |
Tavis Ormandy of the Gentoo Linux Security Audit Team discovered a
stack based buffer overflow in the libTIFF library when reading a TIFF
image with a malformed BitsPerSample tag. Successful exploitation would
require the victim to open a specially crafted TIFF image, resulting in the
execution | |
