FreeBSD Security Advisory FreeBSD-SA-01:53 - Ipfw "me" rules sometimes pass more packets than the administrator realizes when used in conjunction with point-to-point interfaces. Do not use ipfw me, instead give explicit IP addresses.
a2d87cb7ab8f828d0959d0a851d6ddc776013123d5d1775133168ef5b53cc05dFreeBSD Security Advisory FreeBSD-SA-01:40 - The fts routines are vulnerable to a race condition when ascending a file hierarchy, which allows an attacker who has control over part of the hierarchy into which fts is descending to cause the application to ascend beyond the starting point of the file traversal, and enter other parts of the filesystem. If the fts routines are being used by an application to perform operations on the filesystem hierarchy, such as find(1) with a keyword such as -exec or -delete, or rm(1) with the -r flag, these operations can be incorrectly applied to files outside the intended hierarchy, which may result in system damage or compromise. All versions of FreeBSD prior to the correction date including 4.3-RELEASE are vulnerable to this problem.

The control should only allow passive operations such as viewing mail or calendar data. In reality, though, it exposes a function that could allow the web page to manipulate Outlook data. This could enable an attacker to delete mail, change calendar information, or take virtually any other action through Outlook including running arbitrary code on the user's machine. A patch is available. Microsoft FAQ on this issue available here.
99a853d1c4881d0fb19f74361960e1fa307da80894c128435419e4819291eda0Microsoft Security Advisory MS01-045 - Three vulnerabilities have been found in ISA Server 2000. H.323 Gatekeeper Service has a memory leak, The Proxy service has a memory leak, and a cross site scripting bug can be exploited on the error page. Microsoft FAQ on this issue available here.
f383753a52efc4f4f537ff17eba9ff7e73873cfb9e768340af3d7c92518ebf61Netflood.c is useful for testing spoof rules on gateways, testing SYN flood defense mechanisms/configurations (like Checkpoint's SYNdefender module), testing IDS Syn flood/Land attack signatures. It can, of course, be used for engaging in Syn Flood attacks and Land attacks. It also counts number of packets sent.
bda55ddbfb8ea2fe1cd54c3ee88c9a6cb350c464a7d1d47fddb41703ca8ce298Rurf.c is a broadcast ping (smurf) dos attack.

e30d5cf756ffae77685d87c6188e5ef50c5a9115816fc507d00772618b363043NSFOCUS Security Advisory SA2001-06 - A buffer overflow vulnerability has been found in ssinc.dll which is triggered when Microsoft IIS 4.0/5.0 when processes server side include files. An attacker could obtain SYSTEM privilege if he can save html on the server. Discussed in ms01-046.
7b2deeebed5062a304ab98f09b24bf0ddac48ccb7244b9f0b55d3767555c67b4Airsnort is a tool for wireless lans which recovers encryption keys by passively monitoring transmissions, computing the encryption key when enough packets have been gathered. Works on both 40 and 128 bit encryption. Many weaknesses in the WEP 802.11 protocol are discussed here. AirSnort is the first publicly available implementation of this attack. Once enough packets have been gathered, AirSnort can guess the encryption password in under a second. Tested on Linux kernel v2.4.
7e4962b23c6067910ea8fd3d443511714e3d37fd926487be27fdd855cbcb748aThe Linux Intrusion Detection System is a patch which enhances the kernel's security. When it's in effect, many system administration operations can be made impossible even for root. You can turn the security protection on or off on the fly and you can hide sensitive processes and prevent anyone from using ptrace or any other capability on your system. LIDS can also provide raw device and I/O access protection. LIDS FAQ available here.
2357dc349e64dbc6ae294600e876095936e6275a0e43c8dde00964b5d4372ddePrelude is a Network Intrusion Detection system which captures packets and performs data analysis and reporting. Important and current features of Prelude include an IP defragmentation stack and detection plugins with persistent state.
be3c8779ddf9c567462e5553bf2d7d2a4d4a289fcd18d68930b531d67360f039Snort is an open source network intrusion detection system, capable of performing real-time traffic analysis and packet logging on IP networks. It can perform protocol analysis, content searching/matching and can be used to detect a variety of attacks and probes, such as buffer overflows, stealth port scans, CGI attacks, SMB probes, OS fingerprinting attempts, and much more. Includes real time alerting, incorporating alerting mechanisms for syslog, a user specified file, a UNIX socket, or WinPopup messages via smbclient.
