-------------------------------------------------------------------------------- Fedora Update Notification FEDORA-2021-2cb63d912a 2021-01-27 01:17:26.446133 -------------------------------------------------------------------------------- Name : sudo Product : Fedora 33 Version : 1.9.5p2 Release : 1.fc33 URL : https://www.sudo.ws Summary : Allows restricted root access for specified users Description : Sudo (superuser 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. Features include: the ability to restrict what commands a user may run on a per-host basis, copious logging of each command (providing a clear audit trail of who did what), a configurable timeout of the sudo command, and the ability to use the same configuration file (sudoers) on many different machines. -------------------------------------------------------------------------------- Update Information: Security fix for CVE-2021-3156 -------------------------------------------------------------------------------- ChangeLog: * Tue Jan 26 2021 Matthew Miller <mattdm(a)fedoraproject.org> - 1.9.5p2-1 - rebase to 1.9.5p2 Resolves: rhbz#1920611 - fixed CVE-2021-3156 sudo: Heap buffer overflow in argument parsing Resolves: rhbz#1920618 -------------------------------------------------------------------------------- References: [ 1 ] Bug #1917684 - CVE-2021-3156 sudo: Heap buffer overflow in argument parsing https://bugzilla.redhat.com/show_bug.cgi?id=1917684 -------------------------------------------------------------------------------- This update can be installed with the "dnf" update program.
