Suse has a turbulent history with many vulnerabilities fixed at different periods
of time. There is no easy way to prevent a user from gaining a root shell
if that user is allowed to run arbitrary commands via sudo. Also, many
programs (such as editors) allow the user to run commands via shell escapes, thus avoiding sudo's checks. However, on most systems it is possible to prevent shell escapes with sudo's noexec functionality.
A Brief history of sudo(8):
Sudo was first conceived and implemented by Bob Coggeshall and Cliff Spencer around 1980 at the Department of Computer Science at SUNY/Buffalo. It ran on a VAX-11/750 running 4.1BSD. An updated version, credited to Phil Betchel, Cliff Spencer, Gretchen Phillips, John LoVerso and Don Gworek, was posted to the net.sources newsgroup in December of 1985.
In the Summer of 1986, Garth Snyder released and enhanced version of sudo. For the next 5 years, sudo was fed and watered by a handful of folks at CU-Boulder, including Bob Coggeshall, Bob Manchek, and Trent Hein.
In 1991, Dave Hieb and Jeff Nieusma wrote a new version of sudo with an enhanced sudoers format under contract to a consulting firm called "The Root Group". This version was later released under the GNU public license.
In 1994, after maintaining sudo informally within CU-Boulder for some time, Todd Miller made a public release of "CU sudo" (version 1.3) with bug fixes and support for more operating systems. The "CU" was added to differentiate it from the "official" version from "The Root Group".
In 1996, Todd, who had been maintaining sudo for several years in his spare time, brought sudo development under the umbrella of his consulting firm, Courtesan Consulting. Courtesan remains committed to a free sudo and is sponsoring another sudo rewrite as well as continued development of the sudo 1.x code base.
In 1999, the "CU" prefix was dropped from the name since there has been no formal release of sudo from "The Root Group" since 1991 (the original authors now work elsewhere). As of version 1.6, Sudo no longer contains any of the original "Root Group" code and is available with a BSD-style license.
In 2004, Todd incorporated as GratiSoft, Inc. to provide commercial support and enhancements to the sudo community. Please visit http://www.sudo.ws/sudo/support.html for information on commerical support.
sudo, in its current form, is maintained by: Todd Miller <Todd.Miller@courtesan.com>
Todd continues to enhance sudo and fix bugs.
The current stable version is sudo 1.7.4p4, released on September 7, 2010.
Sudo (su "do") allows a system administrator to give certain users (or groups of users) the ability to run some (or all) commands as root while logging all commands and arguments. Sudo operates on a per-command... basis, it is not a replacement for the shell
About: Sudo (su "do") allows a system administrator to give certain users (or groups of users) the ability to run some (or all) commands as root while logging all commands and arguments. Sudo operates on a per-command basis, it is not a replacement for the shell.
Changes: A crash which occurred when the -i flag was used with a uid not in the password database has been fixed. Sudo now operates in the C locale again when doing a match against sudoers. A potential crash when a glob matches a large number of files has been fixed. A compilation problem with certain versions of Heimdal KerberosV has been fixed. When setting the umask, sudo will now use the union of the user's umask and the value set in sudoers. Sudo now stats fewer files when doing a wildcard match.
The current stable version is sudo 1.6.9p7, released on October 25, 2007.
- Sudo version 1.6.3p7 was released on Mar 2, 2001. This fixes the negating of path-type Defaults entries in a boolean context.
- Sudo version 1.6.3p6 was released on Feb 19, 2001. This fixes a potential security problem. So far, the bug does not appear to be exploitable.
- Sudo version 1.6.3p5 was released on Aug 13, 2000. This fixes the listpw and verifypw sudoers options.
