EnGarde Secure Linux v3.0.9 Now Available
Guardian Digital is happy to announce the release of EnGarde
Secure Community 3.0.10 (Version 3.0, Release 10). This release
includes several bug fixes and feature enhancements to Guardian
Digital WebTool and the SELinux policy, several updated packages,
and several new features.
EnGarde Secure Community is a secure distribution of Linux
engineered from the ground-up to provide organizations with the
level of security required to create a corporate Web presence or
even conduct e-business on the Web. It can be used as a Web, DNS,
e-mail, database, e-commerce, and general Internet server where
security is a primary concern.
* Guardian Digital WebTool help system. All of the existing
WebTool modules now have help -- just roll your mouse pointer
over any help-enabled field for assistance. Special thanks to
Ankit Patel and Eric Lubow for all their hard work writing the
help text.
* Guardian Digital WebTool SELinux Control Console. This new
WebTool module gives you greater control over the SELinux
subsystem of EnGarde Secure Linux. With it you may monitor
the audit logs, toggle enforcing mode and booleans, download
the policy to your local computer, and trigger a relabel of
the filesystems.
* A new SELinux policy boolean: httpd_script_remote. This
boolean was added in response to bug #0000093 and grants PHP
and CGI scripts to external websites (such as RSS feeds).
* Major upgrades of apache (from 2.0.59 to 2.2.3), postfix
(2.2.11 to 2.3.3), and snort (2.4.5 to 2.6.0.2).
* The latest stable versions of MySQL (5.0.27), aide (0.12),
asterisk (1.2.13), libapache-mod_mono (1.1.18), mod_perl

RFID with Bio-Smart Card in Linux
In this paper, we describe the integration of fingerprint template
and RF smart card for clustered network, which is designed on Linux
platform and Open source technology to obtain biometrics security.
Combination of smart card and biometrics has achieved in two step
authentication where smart card authentication is based on a
Personal Identification Number (PIN) and the card holder is
authenticated using the biometrics template stored in the smart
card that is based on the fingerprint verification. The fingerprint
verification has to be executed on central host server for
security purposes. Protocol designed allows controlling entire
parameters of smart security controller like PIN options, Reader
delay, real-time clock, alarm option and cardholder access
conditions.

Packet Sniffing Overview
The best way to secure you against sniffing is to use encryption.
While this won't prevent a sniffer from functioning, it will ensure
that what a sniffer reads is pure junk.

The Xinput module (modules/im/ximcp/imLcIm.c) in X.Org libX11 1.0.2
and 1.0.3 opens a file for reading twice using the same file
descriptor, which causes a file descriptor leak that allows local
users to read files specified by the XCOMPOSEFILE environment
variable via the duplicate file descriptor.
http://www.linuxsecurity.com/content/view/125607
* Mandriva: Updated rpm packages fix vulnerability
7th, November, 2006
A heap-based buffer overflow was discovered in librpm when the LANG
or LC_ALL environment variable is set to ru_RU.UTF-8 (and possibly
other locales), which could allow for ser-assisted attackers to
execute arbitrary code via crafted RPM packages.
http://www.linuxsecurity.com/content/view/125622
* Mandriva: Updated jabber package fix SSL support issue
7th, November, 2006
The OpenSSL library was not properly initialized in the jabber SSL

connections on the jabber server. This update corrects this issue.
http://www.linuxsecurity.com/content/view/125623
* Mandriva: Updated pam_ldap packages fix PasswordPolicyReponse
coding error
7th, November, 2006
Pam_ldap does not return an error condition when an LDAP directory
server responds with a PasswordPolicyResponse control response, which
causes the pam_authenticate function to return a success code even if
authentication has failed, as originally reported for xscreensaver.
This might lead to an attacker being able to login into a suspended
system account.
http://www.linuxsecurity.com/content/view/125624

7th, November, 2006
Multiple integer overflows in the WV library in wvWare (formerly
mswordview) before 1.2.3, as used by AbiWord?, KWord, and possibly
other products, allow user-assisted remote attackers to execute
arbitrary code via a crafted Microsoft Word (DOC) file that produces
(1) large LFO clfolvl values in the wvGetLFO_records function or (2)
a large LFO nolfo value in the wvGetFLO_PLF function.
http://www.linuxsecurity.com/content/view/125626
* Mandriva: Updated openssh packages fix vulnerability
8th, November, 2006

http://www.linuxsecurity.com/content/view/125608
+---------------------------------+
| Distribution: Ubuntu | ----------------------------//
+---------------------------------+
* Ubuntu: PHP vulnerability
2nd, November, 2006
Stefan Esser discovered two buffer overflows in the htmlentities()
and htmlspecialchars() functions. By supplying specially crafted
input to PHP applications which process that input with these
functions, a remote attacker could potentially exploit this to
execute arbitrary code with the privileges of the application. This
update also fixes bugs in the chdir() and tempnam() functions, which
did not perform proper open_basedir checks. This could allow local
scripts to bypass intended restrictions.
http://www.linuxsecurity.com/content/view/125548
* Ubuntu: imlib2 vulnerabilities
3rd, November, 2006
M. Joonas Pihlaja discovered that imlib2 did not sufficiently verify
the validity of ARGB, JPG, LBM, PNG, PNM, TGA, and TIFF images. If a
user were tricked into viewing or processing a specially crafted
image with an application that uses imlib2, the flaws could be
exploited to execute arbitrary code with the user's privileges.
http://www.linuxsecurity.com/content/view/125565
* Ubuntu: NVIDIA vulnerability
3rd, November, 2006
Derek Abdine discovered that the NVIDIA Xorg driver did not correctly
verify the size of buffers used to render text glyphs. When
displaying very long strings of text, the Xorg server would crash.
If a user were tricked into viewing a specially crafted series of
glyphs, this flaw could be exploited to run arbitrary code with root
privileges.
http://www.linuxsecurity.com/content/view/125566
* Ubuntu: RPM vulnerability
3rd, November, 2006
An error was found in the RPM library's handling of query reports.
In some locales, certain RPM packages would cause the library to
crash. If a user was tricked into querying a specially crafted RPM
package, the flaw could be exploited to execute arbitrary code with
the user's privileges.
http://www.linuxsecurity.com/content/view/125567
* Ubuntu: imlib2 regression fix
6th, November, 2006
USN-376-1 provided an update to imlib2 to fix several security
