they share file systems with hosts where users can create hardlinks
to symlinks.
Also not affected are the following configurations: a) maildir-style
delivery with the Postfix built-in local or virtual delivery agents;
b) mail delivery with non-Postfix local or virtual delivery agents;
c) mailbox-style delivery with the Postfix built-in virtual delivery
agent when virtual mailbox parent directories have no "group" or
other write permissions.

To all,
The reason I wrote this article was not to explain how to create a hidden
user account. I wrote the article to show you that you can modify the SAM
in real time in a way that is undetectable by ANYONE. This modification
allows you to masquerade any user account as the built-in Administrator.
Christian,
"Continued Access" to a system means that someone has compromised a system
and they have continued access. This implies that the administrators don't
hidden administrative backdoor account for continued access once a
system has been compromised. Once an attacker has compromised a
Microsoft Windows computer system using any method, they can either
leave behind a regular user or hijack a known user account (Such as
ASPNET). This user account will now have all of the rights of the
built-in local administrator account from local or remote connections.
The user will also share the Administrator's desktop and profile. When
inspected by system administrators, the regular user always looks like
it is just part of the built-in user's group. The attacker can also
make the regular user account hard to detect by creating a user with
the username of "ALT-0160", for blank space. Events in the audit log

About:
Easy File Sharing Web Server is an extremely popular web-based file sharing application that has been in use for years.
It is a fast, easy to use commercial, standalone "all-in-one" file-sharing web server.
Customers use a built-in interface to point to files they wish to publish via a menu-driven web application (typically full drives or directories). Files can be shared anonymously, or via EFSWS's built-in user management. EFSWS has built-in SSL encryption to prevent logons from being sent in the clear (as well as all other access). Users log in, and are presented with a menu of files that have been published and that are made available for download.
EFSWS uses the MGH Software "myDB" database plug-in to store db information such as file location, user information (password in the clear), files, forum information, etc. A free db parser is available at:
http://www.mghsoft.com/
Please see vendor site and db engine site for more details.

the bug could be exploited using conventional methods. However, it is possible
to extract information from the database using Time-Based Blind SQL
Injection [3].
Basically, this consists of using some time-taking SQL operations (e.g.
the BENCHMARK() MySQL built-in function) that will delay server responses if
the specific condition is satisfied. By monitoring the response time, it is
possible to know if the conditional expression is True or False.
Using this technique, it is possible to extract the usernames and passwords
needed to authenticate into the Publique! management interface. Database

*** SUMMARY ***
GCALDaemon is an OS-independent Java program that offers two-way synchronization between Google Calendar and various iCalendar compatible calendar applications. GCALDaemon is primarily designed as a calendar synchronizer but it can also be used as a Gmail notifier, Address Book importer, Gmail terminal and RSS feed converter.
Sunbird/Kontact/Firefox/ThunderBird/Mozilla Calendar all share calendars over HTTP, by uploading their file via an HTTP PUT and getting/refreshing their calendar with an HTTP GET. The GCALDaemon's built-in HTTP server keeps this HTTP messages in sync with a specified Google Calendar. An input validation flaw permits to craft an HTTP request with an abnormal content-length value; this malformed request could trigger a denial of service that arises from a Java out of memory fatal error.
*** VULNERABILITY DETAILS ***
Using a crafted HTTP request, an attacker could trigger a denial of service that arises from a java.lang.OutOfMemoryError when the Java heap space is overfilled.
In the file "org/gcaldaemon/core/http/HTTPListener.java", the GCALDaemon's built-in HTTP server parses the HTTP request and the HTTP header parameters without validation checkpoints.

The combination of these features allows a local attacker to hardlink a
root-owned symlink such that the newly created symlink would be
root-owned and would point to a regular file (or another symlink) that
would be written by the Postfix built-in local(8) or virtual(8)
delivery agents, regardless the ownership of the final destination
regular file. Depending on the write permissions of the spool mail
directory, the delivery style, and the existence of a root mailbox,
this could allow a local attacker to append a mail to an arbitrary file
like /etc/passwd in order to gain root privileges.

Aruba Mobility Controller
http://www.arubanetworks.com/products/mobility_controllers.php
Aruba mobility controllers use X.509 certificates to protect access to the web management interface and to provide secure wireless authentication, such as TLS, TTLS, PEAP, and Aruba-specific Captive Portal. By default the controller uses a built-in certificate that is shared by all deployed units across all customers. Administrators are not forced to generate new, implementation-specific key pairs to replace this shared one.
Since the corresponding private key is not protected in any particular way it is possible for a party with access to one of the controllers to retrieve the private key and abuse it to compromise other implementations.
The latest such certificate is serial number 386929 issued by Equifax Secure Certificate Authority, expiring Jun 30, 2011.
To cut the intro blablablas short, I've compiled this video here:

It's about abusing PHP's builtin PRNG functions to attack web applications.
It starts where Stefan Esser's wonderful article "mt_srand and not so random numbers" ( http://www.suspekt.org/2008/08/17/mt_srand-and-not-so-random-numbers/ ) ended.
I've made some improvements to his idea. Since mt_srand()/mt_rand() are very slow (~17 hours to try all possible 2^32 seeds on my AMD Phenom 2.6 ghz machine) and lookup tables are huge (at least 32 GB), I implemented rainbow tables. With a chain length of 10000 and 512k rows, the table size is 11MB and average search takes only about 35 min. Rainbow table parameters can be tuned (longer chains = less space, but slower seed crack, shorter chains and more rows = more space, but less time to crack the seed).
1) Unauthenticated access to critical functions
Unauthenticated attackers are e.g. able to create new user accounts
with administrative "Manager" roles. It is possible to exploit the
built-in "salang" scripting language to read/write files on the file
system (e.g. user configuration with MD5 hashes), connect to other
internal systems or execute arbitrary operating system commands.
