procfs in FreeBSD and possibly other operating systems allows local users to cause a denial of service by calling mmap on the process' own mem file, which causes the kernel to hang.

procfs in FreeBSD and possibly other operating systems allows local users to bypass access control restrictions for a jail environment and gain additional privileges.

Vulnerability in telnetd in FreeBSD 1.5 allows local users to gain root privileges by modifying critical environmental variables that affect the behavior of telnetd.

Buffer overflow in kdc_reply_cipher of libkrb (Kerberos 4 authentication library) in NetBSD 1.5 and FreeBSD 4.2 and earlier, as used in Kerberised applications such as telnetd and login, allows local users to gain root privileges.

ppp utility in FreeBSD 4.1.1 and earlier does not properly restrict access as specified by the "nat deny_incoming" command, which allows remote attackers to connect to the target system.

telnetd in FreeBSD 4.2 and earlier, and possibly other operating systems, allows remote attackers to cause a denial of service by specifying an arbitrary large file in the TERMCAP environmental variable, which consumes resources as the server process...

fingerd in FreeBSD 4.1.1 allows remote attackers to read arbitrary files by specifying the target file name instead of a regular user name.

FreeBSD 4.1.1 and earlier, and possibly other BSD-based OSes, uses an insufficient random number generator to generate initial TCP sequence numbers (ISN), which allows remote attackers to spoof TCP connections.

Buffer overflow in ncurses library allows local users to execute arbitrary commands via long environmental information such as TERM or TERMINFO_DIRS.

Format string vulnerability in pw_error function in BSD libutil library allows local users to gain root privileges via a malformed password in commands such as chpass or passwd.
