This release includes several bug fixes and feature enhancements to the SELinux policy and several updated packages. http://wiki.engardelinux.org/index.php/ReleaseNotes3.0.13 --- 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. http://www.linuxsecurity.com/content/view/125052/171/ --- 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. http://www.linuxsecurity.com/content/view/123570/49/ -------- --> Take advantage of the LinuxSecurity.com Quick Reference Card! --> http://www.linuxsecurity.com/docs/QuickRefCard.pdf +---------------------------------+ | Distribution: Debian | ----------------------------// +---------------------------------+ * Debian: New Linux 2.6.18 packages fix several vulnerabilities 13th, May, 2007 Several local and remote vulnerabilities have been discovered in the Linux kernel that may lead to a denial of service or the execution of arbitrary code. We recommend that you upgrade your kernel package immediately and reboot the machine. If you have built a custom kernel from the kernel source package, you will need to rebuild to take advantage of these fixes. http://www.linuxsecurity.com/content/view/128165 * Debian: New squirrelmail packages fix cross-site scripting 13th, May, 2007 It was discovered that the webmail package Squirrelmail performs insufficient sanitising inside the HTML filter, which allows the injection of arbitrary web script code during the display of HTML email messages. http://www.linuxsecurity.com/content/view/128166 * Debian: New samba packages fix multiple vulnerabilities 15th, May, 2007 Several issues have been identified in Samba, the SMB/CIFS file and print-server implementation for GNU/Linux. When translating SIDs to/from names using Samba local list of user and group accounts, a logic error in the smbd daemon's internal security stack may result in a transition to the root user id rather than the non-root user. http://www.linuxsecurity.com/content/view/128207 * Debian: New qt4-x11 packages fix cross-site scripting vulnerability 15th, May, 2007 ndreas Nolden discovered a bug in the UTF8 decoding routines in qt4-x11, a C++ GUI library framework, that could allow remote attackers to conduct cross-site scripting (XSS) and directory traversal attacks via long sequences that decode to dangerous metacharacters. http://www.linuxsecurity.com/content/view/128209 * Debian: New samba packages fix multiple vulnerabilities 17th, May, 2007 Various bugs in Samba's NDR parsing can allow a user to send specially crafted MS-RPC requests that will overwrite the heap space with user defined data. http://www.linuxsecurity.com/content/view/128228 +---------------------------------+ | Distribution: Fedora | ----------------------------// +---------------------------------+ * Fedora Core 6 Update: php-5.1.6-3.6.fc6 14th, May, 2007 This update fixes a number of security issues in PHP. A heap buffer overflow flaw was found in the PHP 'xmlrpc' extension. A PHP script which implements an XML-RPC server using this extension could allow a remote attacker to execute arbitrary code as the 'apache' user. Note that this flaw does not affect PHP applications using the pure-PHP XML_RPC class provided in /usr/share/pear. http://www.linuxsecurity.com/content/view/128184 * Fedora Core 5 Update: samba-3.0.24-5.fc5 14th, May, 2007 This release of Samba fixes some Serious security bugs, CVE-2007-2444, CVE-2007-2446 and CVE-2007-2447.

The ftdi_sio driver allowed local users to cause a denial of service (memory consumption) by writing more data to the serial port than the hardware can handle, which causes the data to be queued. This requires this driver to be loaded, which only happens if such a device is plugged in. http://www.linuxsecurity.com/content/view/128140 +---------------------------------+ | Distribution: Ubuntu | ----------------------------// +---------------------------------+ * Ubuntu: pptpd vulnerability 14th, May, 2007 A flaw was discovered in the PPTP tunnel server.
