Vulnerabilidades

KDE kppp allows local users to create a directory in an arbitrary location via the HOME environmental variable.

KDE allows local users to execute arbitrary commands by setting the KDEDIR environmental variable to modify the search path that KDE uses to locate its executables.

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.

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.

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

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.

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

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.

The rwho/rwhod service is running, which exposes machine status and user information.

Listening TCP ports are sequentially allocated, allowing spoofing attacks.

Arbitrary command execution via metamail package using message headers, when user processes attacker's message using metamail.

The access permissions for a UNIX domain socket are ignored in Solaris 2.x and SunOS 4.x, and other BSD-based operating systems before 4.4, which could allow local users to connect to the socket and possibly disrupt or control the operations of the program using that socket.

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 in FreeBSD lpd through long DNS hostnames.

Buffer overflow of rlogin program using TERM environmental variable.

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