The sudo manuals no longer require extensive post-processing to hide system-specific features.

Fixes and clarifications to the sudo plugin documentation.

Nanosecond precision file time stamps are now supported on HP-UX.

Previously, only the utmp and utmpx files were updated.

On HP-UX, sudo will now update the utmps file when running a command in a pseudo-tty.

Note: While the software is classified as free, it is actually donationware. Please see the samples Sudoers file below for a real-world example. This allows for central administration while keeping the flexibility to define a user's privileges on a per-host basis.

Sudo's configuration file, the Sudoers file, is setup in such a way that the same Sudoers file may be used on many machines.

There is also an easy way for a user to remove their ticket file, useful for placing in a. This avoids the problem of leaving a root shell where others can physically get to your keyboard. Each subsequent Sudo command updates the ticket for another 5 minutes. When a user invokes Sudo and enters their password, they are granted a ticket for 5 minutes (this timeout is configurable at compile-time).

Sudo uses timestamp files to implement a "ticketing" system.

At CU, all admins use Sudo in lieu of a root shell to take advantage of this logging. When used in tandem with syslogd, the system log daemon, Sudo can log all commands to a central host (as well as on the local host).

Sudo does copious logging of each command, providing a clear audit trail of who did what.

The ability to restrict what commands a user may run on a per-host basis.

Sudo operates on a per-command basis, it is not a replacement for the shell. In addition, other researchers found that the bug could also be exploited on IBM AIX systems.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 app for mac Patch#

Apple declined to comment as it investigates the report however, even without an official confirmation from the Cupertino-based tech giant, a patch is most likely expected for such a serious issue. The researcher said he notified Apple of the issue earlier today. Hickey told ZDNet the bug could be exploited in the recent version of macOS, even after applying the recent security patches Apple released on Monday.

His findings were also privately and independently verified and confirmed to ZDNet by Patrick Wardle, one of today’s leading macOS security experts, and publicly by Will Dormann, a vulnerability analyst at the Carnegie Mellon University’s CERT Coordination Center. “To trigger it, you just have to overwrite argv or create a symlink, which therefore exposes the OS to the same local root vulnerability that has plagued Linux users the last week or so,” Hickey told ZDNet today, prior to sharing a video of the bug in question. Hickey said he tested the CVE-2021-3156 vulnerability and found that with a few modifications, the security bug could be used to grant attackers access to macOS root accounts as well.ĬVE-2021-3156 also impacts MacOS Big Sur (unpatched at present), you can enable exploitation of the issue by symlinking sudo to sudoedit and then triggering the heap overflow to escalate one’s privileges to 1337 uid=0. Latest macOS version also impactedīut as Matthew Hickey, the co-founder of Hacker House, pointed out on Twitter today, the recent version of macOS also ships with the Sudo app. They said that are UNIX-like operating systems are also impacted, but most security researchers thought the bug might impact BSD, another major OS that also ships with the Sudo app. In their report last week, Qualys researchers said they only tested the issue on Ubuntu, Debian, and Fedora. The only condition to exploit this bug was that an attacker gain access to a system, which researchers said could be done by either planting malware on a device or brute-forcing a low-privileged service account. Qualys researchers discovered that they could trigger a “ heap overflow” bug in the Sudo app to change the current user’s low-privileged access to root-level commands, granting the attacker access to the whole system.

The vulnerability, disclosed last week as CVE-2021-3156 (aka Baron Samedit) by security researchers from Qualys, impacts Sudo, an app that allows admins to delegate limited root access to other users.

A British security researcher has discovered today that a recent security flaw in the Sudo app also impacts the macOS operating system, and not just Linux and BSD, as initially believed.
