Freebsd: >> Freebsd >> 2.2 Security Vulnerabilities
Race condition in the UFS and EXT2FS file systems in FreeBSD 4.2 and earlier, and possibly other operating systems, makes deleted data available to user processes before it is zeroed out, which allows a local user to access otherwise restricted information.

IPFilter 3.4.16 and earlier does not include sufficient session information in its cache, which allows remote attackers to bypass access restrictions by sending fragmented packets to a restricted port after sending unfragmented packets to an unrestricted port.

The system configuration control (sysctl) facility in BSD based operating systems OpenBSD 2.2 and earlier, and FreeBSD 2.2.5 and earlier, does not properly restrict source routed packets even when the (1) dosourceroute or (2) forwarding variables are set, which allows remote attackers to spoof TCP connections.
