The Red Hat Linux su program does not log failed password guesses if the su process is killed before it times out, which allows local attackers to conduct brute force password guessing.

Vacation program allows command execution by remote users through a sendmail command.

Buffer overflow in Sun's ping program can give root access to local users.

cmdtool in OpenWindows 3.0 and XView 3.0 in SunOS 4.1.4 and earlier allows attackers with physical access to the system to display unechoed characters (such as those from password prompts) via the L2/AGAIN key.

NIS finger allows an attacker to conduct a denial of service via a large number of finger requests, resulting in a large number of NIS queries.

Buffer overflow in BNU UUCP daemon (uucpd) through long hostnames.

Solaris rpc.mountd generates error messages that allow a remote attacker to determine what files are on the server.

SunOS rpc.cmsd allows attackers to obtain root access by overwriting arbitrary files.

The NIS+ rpc.nisd server allows remote attackers to execute certain RPC calls without authentication to obtain system information, disable logging, or modify caches.

Teardrop IP denial of service.

A later variation on the Teardrop IP denial of service attack, a.k.a. Teardrop-2.

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

Land IP denial of service.

The AIX FTP client can be forced to execute commands from a malicious server through shell metacharacters (e.g. a pipe character).

In SunOS or Solaris, a remote user could connect from an FTP server's data port to an rlogin server on a host that trusts the FTP server, allowing remote command execution.

Buffer overflow in eeprom in Solaris 2.5.1 and earlier allows local users to gain root privileges via a long command line argument.

Buffer overflow in chkey in Solaris 2.5.1 and earlier allows local users to gain root privileges via a long command line argument.

SunOS 4.1.4 on a Sparc 20 machine allows local users to cause a denial of service (kernel panic) by reading from the /dev/tcx0 TCX device.

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

NFS cache poisoning.
