Security
Members of the Full Disclosure mailing list recently got
a little more disclosure than they had been looking for. It
turns out that a bug in the mailman list manager enabled a
suitably clever attacker to pull arbitrary files from the server. In
particular, the list of mailman accounts and passwords was taken from the
Full Disclosure server. Since people tend to use username and password
combinations in more than one place, it is entirely possible that the
information obtained could be used to attack user accounts elsewhere.
The bug was in this bit of code:
def true_path(path):
"Ensure that the path is safe by removing .."
path = path.replace('../', '')
path = path.replace('./', '')
return path[1:]
At first glance, it would appear that the above checks would remove any
directory traversal attempts. If, however, the URL contains a string like
".../....///", the string replacements performed will leave a
simple "../" in the path.
In retrospect, there is an obvious error here. The checks in the function
above perform some transformations to the input string, but never actually
verify that the resulting string does not violate the constraints they are
supposed to be enforcing. Such
code will likely always be exploitable in one way or another. The
short-term fix changes the above logic by splitting the path into
components and dealing with each component separately.
The bigger error, however, and one which is not addressed by the short-term
fix, is to allow the request to proceed at all if undesirable elements are
found. Assuming the code is reasonably well done, it should not generate
URLs which later need to be fixed up by the input validation routines. So
if something comes through which looks like a directory traversal attempt,
the more prudent action would be to reject the request outright. Hostile
input suggests hostile intent; it should be responded to accordingly.

Security reports
The Mozilla Foundation has issued a
short-term response to Mozilla's vulnerability to a homograph spoofing
attack using international domain names (IDNs). " In the forthcoming
Mozilla Firefox 1.0.1 and Mozilla 1.8 Beta releases, IDN support will be
disabled (bug 282270). For those users that need it, an XPI will be
released to turn IDN support back on (bug 282269)." Gervase Markham
has also provided some clarification and possible long-term solutions on
his web
log.

Michael Kerrisk noticed an insufficient permission checking in the shmctl()
function. Any process was permitted to lock/unlock any System V shared
memory segment that fell within the the RLIMIT_MEMLOCK limit (that is the
maximum size of shared memory that unprivileged users can acquire). This
allowed am unprivileged user process to unlock locked memory of other
processes, thereby allowing them to be swapped out. Usually locked shared
memory is used to store passphrases and other sensitive content which must
not be written to the swap space (where it could be read out even after a
reboot). (CAN-2005-0176)
OGAWA Hirofumi noticed that the table sizes in nls_ascii.c were incorrectly

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: |
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
parsing routines. These routines can overflow a buffer if passed a very
long URL. If an attacker is able to find an application using libxml2 that
parses remote resources and allows them to influence the URL, then this
flaw could be used to execute arbitrary code. |
