Security
This week's "new vulnerabilities" section is somewhat longer than usual; a
rather large number of packages have been revealed to have
vulnerabilities. This surge in updates is a result of the posting of 44 vulnerabilities found by
students in a security class taught by Daniel J. Bernstein.
There is no doubt that Mr. Bernstein has done us a favor by having his
students find these problems, and by disclosing them. With luck, he is
also teaching his students to avoid the creation of such vulnerabilities.
Not everybody is pleased with how the problems were disclosed, however.
The usual, accepted technique is to alert the maintainer of the affected
software first, and to give them a bit of time in which to prepare and
distribute a patch. In this way, the full, public disclosure of the
vulnerability can be accompanied by an update.
That was not the path followed by Mr. Bernstein; instead, he opted to
dispense with the prior notification to the maintainer, and to simply disclose the
vulnerabilities publicly from the outset. The result has been a major
scramble on the parts of maintainers and distributors who have found
themselves trying to deal with a large pile of problems which have already
been broadcast to the world.
Mr. Bernstein is not known for being apologetic in general, and he
certainly was not in this case. In fact, he regretted that it took the reports one day to
make it to Bugtraq: "It certainly wasn't my intention to give the
authors an extra day of self-delusion." In a
different discussion he has made his opinion clear:
On the contrary. Immediate full disclosure, with a working exploit,
punishes the programmer for his bad code. He panics; he has to rush
to fix the problem; he loses users.
You're whining that punishment is painful. You're ignoring the effect
that punishment has on future behavior. It encourages programmers to
invest the time and effort necessary to eliminate security problems.
So, it seems, the real solution to security problems is to punish
programmers who release insecure code. There could be something to be said
for this point of view: programmers who have been burned in this way might
well find themselves inspired to pay more attention the next time around.
The unfortunate side effects of immediate disclosure, however, include the
punishment of users and distributors, and the possible creation of rushed,
inadequate fixes. Compassion for people - other than the original
developer - who are affected by vulnerabilities might suggest that allowing
the developer to prepare a fix prior to disclosure might be the better
approach.

Brief items
The phpBB bulletin board package contains an input validation problem which
can allow the hosting site to be compromised. This vulnerability is being
actively exploited, and there is apparently a worm in circulation as well.
Click below to read the CERT advisory this problem; upgrading to version
2.0.11 fixes the problem.

libgd2: buffer overflows in PNG handling

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. |

CVE #(s): | CAN-2004-0110

| Description: |
Yuuichi Teranishi discovered a flaw in libxml2 versions prior to 2.6.6.
When fetching a remote resource via FTP or HTTP, libxml2 uses special

php: remotely exploitable memory errors

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). |
