Multiple TCP/IP implementations may use statistically predictable initial sequence numbers

Overview Attacks against TCP initial sequence number generation have been discussed for some time now. It has long been recognized that the ability to know or predict ISNs can lead to TCP connection hijacking or spoofing. What was not previously illustrated was just how predictable one...

CVE-2000-0916

CVE-2000-0916 is a historical TCP-ISN prediction vulnerability affecting FreeBSD 4.1.1 and earlier (and possibly other BSD-based OSes). The root cause is an insufficient random initial sequence number (ISN) generator, enabling remote attackers to spoof TCP connections. Several connected sources c...

CVE-2000-0703

CVE-2000-0703 affects suidperl (sperl). The vulnerability arises because suidperl does not properly cleanse the escape sequence "~!" before invoking /bin/mail to report errors. This enables local users to gain privileges by setting the interactive environmental variable and running suidperl with ...
