1bcc19e68e14b708413f9da768c55ffc6991940d1134e29017b7145086ed9a4bNetwork Associates Security Advisory COVERT-2001-01 - BIND v8.2.2 to 8.2.3-T9B contains buffer overflows that allows a remote attacker to execute arbitrary code. The overflow is in the initial processing of a DNS request and therefore does not require an attacker to control an authoritative DNS server. This vulnerability not dependent upon configuration options and affects both recursive and non-recursive servers. Additional remote format string and buffer overflows affect v8.2 through 8.2.3-T9B and v4.9.3 to v4.9.7. ISC's description of the problems available here.
0dc7c588880d158bf0463b6985c16a22f3debb3dc8fa15807d452573395d7286Ettercap is a network sniffer/interceptor/logger for switched LANs. It uses ARP poisoning and the man-in-the-middle technique to sniff all the connections between two hosts. Features character injection in an established connection - you can inject characters to server (emulating commands) or to client (emulating replies) while maintaining the connection alive! Integrated into a easy-to-use and powerful ncurses interface.

bcbac6b73e719d6616d1e1851da6d457f568a7ce545c3c6e33a6048ce1c0aceeNaptha v1.1 is a denial of service attack against many OS's which uses established TCP connections to create a resource starvation attack. Includes three tools - bogusarp makes a bogus entry in the router's arp cache so it actually puts packets with our faked source address on the Ethernet, synsend, and srvr which replaces ackfin from Naptha 1.0. Tested against Windows 95, 98 and NT4 and more. Compiles on Linux 2.2.x, OpenBSD 2.7, FreeBSD 4.0.

c16ac5bdc4e051947b73224fd9ce4ee3520b8642faad979a56aa2d408efed275Due to a various race conditions in the init level editing script /sbin/rctab it is possible for any local user to overwrite any system's file with arbitrary data. This may result in denial of service attack, local or even remote root compromise, if root runs the /sbin/rctab script. Tested against SuSE 7.0.

5962857e51380ddd9c8779fffaabc0d7d0b7a29097786414f377c5d1d18e92dbDebian Security Advisory DSA-021-1 - The mod_rewrite module for Apache has a remote vulnerability which may allow a remote attacker to gain access to arbitrary files. Users of the mod_rewrite module are advised to upgrade. In addition, htdigest and htpasswd use tempfiles insecurely. Since they are not setuid, impact is minimal.

It is useful for identifying high bandwidth users, intrusive telnet sessions, denial of service attacks, and scans. Ipaudit stores counts of bytes and packets for every combination of host/port pairs and protocol. It also includes scripts which automatically generate webified reports, CGI scripts which organize web presentation, and the utilities "total" and "ipstrings" which can be used to investigate network traffic records from the command line.

To eliminate these problems, we provide update packages that completely disregard the LD_* variables upon runtime-linking of a binary that has an effective uid different from the caller's userid.
