04176a26ae4765b00ef4e4f75faf0e72600d8e13e260d89cfd33ce9a9697bc98The IE 5 Web Proxy Auto-Discovery (WPAD) feature enables web clients to automatically detect proxy settings without user intervention. The algorithm used by WPAD prepends the hostname "wpad" to the fully-qualified domain name and progressively removes subdomains until it either finds a WPAD server answering the hostname or reaches the third-level domain. A vulnerability arises because in international usage, the third-level domain may not be trusted. A malicious user could set up a WPAD server and serve proxy configuration commands of his or her choice. Microsoft FAQ here.

89820d58bc30853377078b5112bf63b242c99bfc1dcb91617712124607daf73fMicrosoft has released a patch for a vulnerability in the SSL ISAPI filter that ships with IIS and other microsoft products which could allow plaintext to be sent back to the data's owner. A FAQ about this vulnerability is here.
87a0a7a5e8e96807db49642cd72ae20247b0809d7717d3d6245dfc2c75b1135fThe version of dump that was distributed with Debian GNU/Linux 2.1 suffers from a problem with restoring symbolic links. The new version uses lchown instead of chown, fixing a possible security problem when restoring symlinks (a malicious user could use this to deliberately corrupt the ownership of important system files). Debian security website here.
d6ca5c12e1090ef63a7880ef69eb09531e1db975d5bfe60b3bafad55afdc3887A vulnerability has been found that the installation of Internet Explorer 5 introduces in Windows NT through the Task Scheduler service. This vulnerability makes it possible for a User to become a member of the Administrators group if he/she can do an interactive logon. The Task Scheduler service is an "improved" version of the usual Schedule service - they are not the same thing. The Schedule service is replaced by the Task Scheduler when Internet Explorer 5 is installed on Windows NT. Microsoft security bulletin 51 addresses this issue and is available here.

This advisory addresses the details of the bug discovered, the details are somewhat focused on the ability to exploit the bug in SSH compiled with RSAREF2, but its extensible to any software product that uses RSAREF2.
527168062ffc62dfc807ebe43c1e9bb63bab56ab4c45d4ed0623b4acd4bf4dccNetscape Enterprise Server and Netscape FastTrack Server are widely used Internet web servers. Internet Security Systems (ISS) X-Force has discovered a vulnerability in Netscape Enterprise Server and Netscape FastTrack Server, as well as in the Administration Server supplied with both. There is a buffer overflow in the HTTP Basic Authentication that can be used to execute code on the machine as SYSTEM in Windows NT or as root or nobody in Unix, without requiring authentication. The Administration Service runs as root in Unix, the Application Server runs as the user nobody by default.

dfe4cb29305c619dc0a0aca5b11b2bd397baccf3076b48f03457f66f299ab42eNetPeek is a GUI-based network monitoring and diagnosis tool. It captures packets from the local network and displays them to the user in two forms: a short one-line description similar to that produced by tcpdump, and a long form that displays the contents of all fields within the packets in full. NetPeek also includes some useful network analysis tools similar to ping, hostname lookup, netstat, rpcinfo, and ifconfig.

The connection is internally forwarded to sendmail and does not require sendmail to be running on port 25. Clients which support this currently are Netscape Messenger, Microsoft Outlook, and Microsoft Outlook Express.

0b34ee09d0cbd1db6fb166d906bec18b73d868fd203c6728baf0e90b8e107330Bastille Linux aims to be the most comprehensive, flexible and educational Security Hardening Program for Red Hat Linux. Virtually every task it performs is optional, providing immense flexibility. It also educates the user regarding the topic at hand before asking any question. The interactive nature allows the program to be more thorough when securing, while the educational component produces an admin who is less likely to compromise the increased security.
84bd4c8d84f91c54e1931a348fdbb0ade81ac8f75d3f5e5777b1655b8413d7a8PortSentry is part of the Abacus Project suite of security tools. It is a program designed to detect and respond to port scans against a target host in real-time. It runs on TCP and UDP sockets and works on most UNIX systems. Advanced stealth detection modes are available under Linux only and detect SYN, FIN, NULL, XMAS, and Oddball packet scans. All modes support real-time blocking and reporting of violations.
