Buffer overflow in BSD-based telnetd telnet daemon on various operating systems allows remote attackers to execute arbitrary commands via a set of options including AYT (Are You There), which is not properly handled by the telrcv function.

time server daemon timed allows remote attackers to cause a denial of service via malformed packets.

rwho daemon rwhod in FreeBSD 4.2 and earlier, and possibly other operating systems, allows remote attackers to cause a denial of service via malformed packets with a short length.

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.

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 FreeBSD fts library routines allows local user to modify arbitrary files via the periodic program.

The undocumented semconfig system call in BSD freezes the state of semaphores, which allows local users to cause a denial of service of the semaphore system by using the semconfig call.

ip_input.c in BSD-derived TCP/IP implementations allows remote attackers to cause a denial of service (crash or hang) via crafted packets.

Operating systems with shared memory implementations based on BSD 4.4 code allow a user to conduct a denial of service and bypass memory limits (e.g., as specified with rlimits) using mmap or shmget to allocate memory and cause page faults.

A buffer overflow in lsof allows local users to obtain root privilege.

IP fragmentation denial of service in FreeBSD allows a remote attacker to cause a crash.

FTP servers can allow an attacker to connect to arbitrary ports on machines other than the FTP client, aka FTP bounce.

Buffer overflow in Xt library of X Windowing System allows local users to execute commands with root privileges.

Sysinstall in FreeBSD 2.2.1 and earlier, when configuring anonymous FTP, creates the ftp user without a password and with /bin/date as the shell, which could allow attackers to gain access to certain system resources.

Buffer overflow of rlogin program using TERM environmental variable.

Jolt ICMP attack causes a denial of service in Windows 95 and Windows NT systems.

Buffer overflow in ppp program in FreeBSD 2.1 and earlier allows local users to gain privileges via a long HOME environment variable.

Buffer overflow in lpr, as used in BSD-based systems including Linux, allows local users to execute arbitrary code as root via a long -C (classification) command line option.

Local user gains root privileges via buffer overflow in rdist, via lookup() function.
