Certain versions of AIX and HP/UX contained a bug in the way the OS handled the connect system call. The connect call is used to initiate a connection on a socket. Because of the flaw in the handling code under AIX certain versions will reboot when given two connects, one to a fixed port (a number of different ports were found to trigger this behaviour) and then another random port connection immediately thereafter.
A vulnerability exists in the eject program shipped with Irix 6.2 from Silicon Graphics. By supplying a long argument to the eject program, it is possible to overwrite the return address on the stack, and execute arbitrary code as root. Eject is normally used to eject removeable media from the system, and as such is setuid root to allow for any user at the console to perform eject operations.
A vulnerability exists in the X libraries as supplied with Silicon Graphics IRIX operating system. By placing a carefully constructed buffer as the argument to the -xrm option, an attacker can execute arbitrary code.
SGI's IRIX 5.x and 6.x operating system include a utility called /usr/lib/netaddpr. This program can be used by privledged users to add network printing devices to the system. A race condition exists in this program that could allow any "privledged" user to obtain root access. The netaddpr program is shipped setuid root. As part of its execution, it creates a file in /var/tmp with the file template printersXXXXXX. Because the creation of the file and the actual opening of the file are independant events, there exists a window, during which time an attacker can replace the file with a symbolic link. By making this link point to, for instance, /.rhosts, an attacker can elevate their privledges to that of root.
NT Workstations and Servers must have unique hostnames if they reside on the same network. Should an NT host attempt to use an existing hostname, the second server (with the new duplicate name) will fail to start its workstation and server services. A situation has been noted wherein a Win95 host may register the victim hostname (with a WINS server) by setting the Win95 workgroup name equal to the victim's hostname. The next time the victim host is rebooted, it will fail to start the workstation and server services as the WINS server will report that the hostname is claimed by the Win95 host.
Aspppd is a tool shipped with Solaris for dial up PPP access. This tool creates files in the /tmp directory insecurely (in particular /tmp/.asppp.fifo) allowing other users to link to these files an possibly elevate their privelages. This program is not by default shipped with SUID root privelages so an attacker will therefore only be able to write to files (via a symlink attack) as the user exectuing aspppd.
A vulnerability in ColdFusion allows pages encrypted with the CFCRYPT.EXE utility to be decrypted. A program that decrypts ColdFusion's encryption has been discovered, making the source code for all propietary CFML applications available to those with access to their encrypted form.
This PERL script can be used to execute commands on IIS Unicode vulnerable servers. It makes use of the 'Socket' library and checks for the presence of cmd.exe. If it is not present, it copies the cmd.exe to something else and then uses it. The script then sends a GET request to the server with the command to be executed.
A buffer overflow condition has been found in sdtcm_convert which may be exploited to obtain root access.
A vulnerability exists in Sun's power management software under Solaris versions 2.4-2.6. The sys-suspend program is initiated when a user runs the program, or presses the power key on a sun keyboard. This program moves the contents of memory to the disk, and powers down the system. As part of this shutdown procedure, it runs xlock to prevent a user from resuming the machine and accessing the logged in account. The vulnerability that exists is due to the order in which sys-suspend performs its operations. As xlock is run by this program, it executes after the suspension begins. Upon a resume, there is a window of time during which any data typed at the keyboard is passed to whatever X application last had focus. If this was an xterm, arbitrary commands can be issued. In the even the user who was logged in was root, system security can be entirely subverted.
