Brief items
Remember Habeas? This is the company which copyrighted a bit of haiku,
then restricted the right to include that "work of art" in the headers of
an email message. Only non-spam messages could contain the poem without
violating the license. The idea was that mail filters could look for the
Habeas mark and, upon finding it, deliver the mail with confidence that it
was legitimate.
The folks at Habeas were, apparently, surprised to discover that spammers
are not as respectful as one might like of copyright law - or much of
anything else. It did not take them all that long to start including the
Habeas headers in their solicitations, especially once they figured out
that filters like SpamAssassin gave a strong bonus to such messages. Rather
than being a guarantee of legitimacy, the Habeas headers quickly became one
of the most reliable indicators of spam. The SpamAssassin bonus came out,
and Habeas disappeared from view.
The company is still there, however, and they have not given up. A new press
release issued by the company celebrates the fact that
SpamAssassin 3.0 once again gives a bonus to Habeas-marked mail.
There is a new twist, however: Habeas now implements an online whitelist of
senders whose mail is really thought to be legitimate. Strangely
enough, getting onto the whitelist requires that a fee be paid to Habeas.
This new service might just work for certain kinds of commercial emailers,
as long as Habeas sticks to its anti-spam standards. We may be seeing the
beginning of a shift to a reputation-based mechanism for the filtering of
email. Blacklists were clearly the first step in that direction, but they
are limited in their scope. A scheme which can track positive reputations
might, just, bring a finer degree of control to the spam filtering
problem. Or it might just herald an era where purchasing yet another
useless digital certificate will be required to get email delivered at
all. Either way, it is a development worth watching.

Paul Starzetz has discovered a set of security holes in the kernel ELF
loader; click below for the details. Essentially, bugs in how the kernel
interprets binaries could conceivably be exploited by a local attacker to
obtain root privileges or leak information from the kernel.
Paul discusses 2.4, but
fixes for these problems have just been
merged for 2.6 as well. Expect a
set of distributor updates in the near future.

libgd2: buffer overflows in PNG handling

| Created: | October 29, 2004 |

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. |

php: remotely exploitable memory errors
| Package(s): | php |
CVE #(s): | CAN-2004-0594
|
| Created: | July 14, 2004 |
Updated: | February 7, 2005 |
| Description: |
Stefan Esser has issued an advisory regarding a
remotely exploitable hole in PHP (through version 4.3.7). If the
memory_limit feature is in use (as it should be, to prevent denial
of service attacks), allocation failures can be forced at highly
inopportune times, and those failures can be exploited to execute arbitrary
code. The exploit is described as "quite easy," and it can be done
regardless of whether Apache1 or Apache2 is in use. Upgrading to PHP 4.3.8 fixes the
problem; yesterday's PHP 5.0 release also contains the fix (but the
final release candidate did not). |

PostgreSQL: Insecure temporary file use in make_oidjoins_check

CVE #(s): | CAN-2004-0977

| Created: | October 18, 2004 |
Updated: | December 20, 2004 |
| Description: |
The make_oidjoins_check script insecurely creates temporary files in
world-writeable directories with predictable names. A local attacker could
create symbolic links in the temporary files directory, pointing to a valid
file somewhere on the filesystem. When make_oidjoins_check is called, this
would result in file overwrite with the rights of the user running the
utility, which could be the root user. |

Improper verification of header fields lets an attacker make the pppd
server access memory it isn't allowed to, and crash the server. There is
no possibility of code execution, as there is no data being copied, just a
pointer dereferenced. It is not even entirely clear that this vulnerability can be exploited to deny service to anybody other than the attacker.
