RHBA-2018:1992 - sudo bug fix update
Synopsis
sudo bug fix update
Type/Severity
Bug Fix Advisory None
Topic
Updated sudo packages that fix one bug are now available for Red Hat Enterprise Linux 7.
Description
The sudo packages contain the sudo utility which allows system administrators to provide certain users with the permission to execute privileged commands, which are used for system management purposes, without having to log in as root.
This update fixes the following bug:
- Previously, when running a command through sudo that had the I/O logging enabled, a parent process of the command was occasionally blocked in the poll() function execution, waiting for an event on the /dev/ptmx file descriptor. Consequently, a deadlock occurred and sudo might leave the process of the command in an unresponsive state. This update adds a pseudoterminal cleanup logic, and sudo no longer causes a deadlock in the described scenario. (BZ#1582155)
Users of sudo are advised to upgrade to these updated packages, which fix this bug.
Solution
Before applying this update, make sure all previously released errata relevant to your system have been applied.
