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.

* Mandriva: Updated kdelibs packages fix KHTML vulnerability
2nd, February, 2007
FIXME Konqueror 3.5.5 does not properly parse HTML comments in title
tags, which allows remote attackers to conduct cross-site scripting
(XSS) attacks and bypass some XSS protection schemes by embedding
certain HTML tags within a comment, a related issue to CVE-2007-0478.
http://www.linuxsecurity.com/content/view/126861
* Mandriva: Updated mpg123 packages fix DoS vulnerability.
2nd, February, 2007
The http_open function in httpget.c in mpg123 before 0.64 allows
remote attackers to cause a denial of service (infinite loop) by
closing the HTTP connection early. Packages have been patched to
correct this issue.
http://www.linuxsecurity.com/content/view/126862
* Mandriva: Updated wireshark packages fix multiple vulnerabilities
3rd, February, 2007
Vulnerabilities in the LLT, IEEE 802.11, HTTP, and TCP dissectors
were
discovered in versions of wireshark less than 0.99.5, as well as
various other bugs. This updated provides wireshark 0.99.5 which is
not vulnerable to these
issues.
http://www.linuxsecurity.com/content/view/126863
* Mandriva: Updated samba packages address multiple vulnerabilities
5th, February, 2007
A logic error in the deferred open code for smbd may allow an
authenticated user to exhaust resources such as memory and CPU on the
server by opening multiple CIFS sessions, each of which will normally
spawn a new smbd process, and sending each connection into an
infinite..
http://www.linuxsecurity.com/content/view/126893
* Mandriva: Updated gd packages fix DoS vulnerability.
6th, February, 2007
Buffer overflow in the gdImageStringFTEx function in gdft.c in the GD
Graphics Library 2.0.33 and earlier allows remote attackers to cause
a denial of service (application crash) and possibly execute
arbitrary code via a crafted string with a JIS encoded font.
http://www.linuxsecurity.com/content/view/126919
* Mandriva: Updated libwmf packages fix embedded gd DoS
vulnerability.
6th, February, 2007
Buffer overflow in the gdImageStringFTEx function in gdft.c in the GD
Graphics Library 2.0.33 and earlier allows remote attackers to cause
a denial of service (application crash) and possibly execute
arbitrary code via a crafted string with a JIS encoded font. Libwmf
uses an embedded copy of the gd source and may also be affected by
this issue. Packages have been patched to correct this issue.
http://www.linuxsecurity.com/content/view/126920
* Mandriva: Updated postgresql packages address multiple
vulnerabilities
6th, February, 2007
Jeff Trout discovered that the PostgreSQL server did not sufficiently
check data types of SQL function arguments in some cases. A user
could then exploit this to crash the database server or read out
arbitrary locations of the server's memory, which could be used to
retrieve database contents that the user should not be able to see.
Note that a user must be authenticated in order to exploit this
(CVE-2007-0555).
http://www.linuxsecurity.com/content/view/126921
* Mandriva: Updated php packages to address multiple issues
6th, February, 2007
PHP 5.2.0 and 4.4 allows local users to bypass safe_mode and
open_basedir restrictions via a malicious path and a null byte before
a ";" in a session_save_path argument, followed by an allowed path,
which causes a parsing inconsistency in which PHP validates the
allowed path but sets session.save_path to the malicious path.
http://www.linuxsecurity.com/content/view/126922
* Mandriva: Updated gtk+2.0 packages address DoS, LSB issues, several
bugs
7th, February, 2007
The GdkPixbufLoader function in GIMP ToolKit (GTK+) in GTK 2 (gtk2)
allows context-dependent attackers to cause a denial of service
(crash) via a malformed image file. (CVE-2007-0010)
http://www.linuxsecurity.com/content/view/126933
* Mandriva: Updated kernel packages fix multiple vulnerabilities and
bugs
7th, February, 2007
The isdn_ppp_ccp_reset_alloc_state function in
drivers/isdn/isdn_ppp.c in the Linux 2.4 kernel before 2.4.34-rc4, as
well as the 2.6 kernel, does not call the init_timer function for the
ISDN PPP CCP reset state timer, which has unknown attack vectors and
results in a system crash. (CVE-2006-5749)

| Distribution: Ubuntu | ----------------------------//
+---------------------------------+
* Ubuntu: PostgreSQL vulnerabilities
5th, February, 2007
Jeff Trout discovered that the PostgreSQL server did not sufficiently
check data types of SQL function arguments in some cases. An
authenticated attacker could exploit this to crash the database
server or read out arbitrary locations in the server's memory, which
could allow retrieving database content the attacker should not be
able to see. (CVE-2007-0555)
http://www.linuxsecurity.com/content/view/126876
* Ubuntu: Bind vulnerabilities
5th, February, 2007
A flaw was discovered in Bind's DNSSEC validation code. Remote
attackers could send a specially crafted DNS query which would cause
the Bind server to crash, resulting in a denial of service. Only
servers configured to use DNSSEC extensions were vulnerable.
http://www.linuxsecurity.com/content/view/126894
* Ubuntu: Samba vulnerabilities
6th, February, 2007
A flaw was discovered in Samba's file opening code, which in certain
situations could lead to an endless loop, resulting in a denial of
service.
http://www.linuxsecurity.com/content/view/126916
* Ubuntu: KDE library vulnerability
6th, February, 2007
Jose Avila III and Robert Tasarz discovered that the KDE HTML library

* Ubuntu: PostgreSQL 8.1 regression
6th, February, 2007
USN-417-1 fixed several vulnerabilities in the PostgreSQL server.

problem. We apologize for the inconvenience.
