The SANS top-20 list
SANS has posted a new version of its 20 most critical Internet security
vulnerabilities list. As always, this list is a good starting point
for those looking for potential security problems on their networks. Here
are some highlights from the current version:
- Five of the twenty items concern Windows and other Microsoft
software.
- There are ten vulnerabilities in "cross-platform applications"
listed. Some of these (commercial DNS servers, for example) do not
apply to most Linux systems. But others do, including anti-virus
software (ClamAV in particular), PHP-based applications (several
vulnerabilities), database managers, file-sharing applications, media
players, and Mozilla-based browsers.
- There are only two Unix-specific vulnerabilities, and one of those is
a general item on Mac OS X. The other vulnerability is
"configuration weaknesses," with an emphasis on SSH attacks.
Once upon a time, this list was evenly divided between Windows and Unix
vulnerabilities. A casual reading of the current list suggests that things
have shifted in favor of Unix-based systems. While it may be true that
Unix-based systems are easier to keep secure on the net, there is still no
reason to be overly complacent. A system compromised by way of a Firefox
or PHP vulnerability is still compromised.

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 of arbitrary code. |
