Vulnerabilidades

KDE klock allows local users to kill arbitrary processes by specifying an arbitrary PID in the .kss.pid file.

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

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

TCP RST denial of service in FreeBSD.

Buffer overflow in NFS mountd gives root access to remote attackers, mostly in Linux systems.

The chpass command in OpenBSD allows a local user to gain root access through file descriptor leakage.

The at program in IRIX 6.2 and NetBSD 1.3.2 and earlier allows local users to read portions of arbitrary files by submitting the file to at with the -f argument, which generates error messages that at sends to the user via e-mail.

FreeBSD allows local users to conduct a denial of service by creating a hard link from a device special file to a file on an NFS file system.

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

FreeBSD T/TCP Extensions for Transactions can be subjected to spoofing attacks.

Denial of Service vulnerabilities in BIND 4.9 and BIND 8 Releases via CNAME record and zone transfer.

Inverse query buffer overflow in BIND 4.9 and BIND 8 Releases.

Denial of Service vulnerability in BIND 8 Releases via maliciously formatted DNS messages.

FreeBSD mmap function allows users to modify append-only or immutable files.

mmap function in BSD allows local attackers in the kmem group to modify memory through devices.

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.

ICMP messages to broadcast addresses are allowed, allowing for a Smurf attack that can cause a denial of service.

Teardrop IP denial of service.

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 open() function in FreeBSD allows local attackers to write to arbitrary files.

File creation and deletion, and remote execution, in the BSD line printer daemon (lpd).

The asynchronous I/O facility in 4.4 BSD kernel does not check user credentials when setting the recipient of I/O notification, which allows local users to cause a denial of service by using certain ioctl and fcntl calls to cause the signal to be sent to an arbitrary process ID.

rpc.mountd on Linux, Ultrix, and possibly other operating systems, allows remote attackers to determine the existence of a file on the server by attempting to mount that file, which generates different error messages depending on whether the file exists or not.

DNS cache poisoning via BIND, by predictable query IDs.
