An update for sudo is now available for Red Hat Enterprise Linux 6 and Red Hat Enterprise Linux 7. Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ==================================================================== Red Hat Security Advisory Synopsis: Moderate: sudo security update Advisory ID: RHSA-2016:2872-01 Product: Red Hat Enterprise Linux Advisory URL: https://access.redhat.com/errata/RHSA-2016:2872.html Issue date: 2016-12-06 CVE Names: CVE-2016-7032 CVE-2016-7076 ==================================================================== 1. Summary: An update for sudo is now available for Red Hat Enterprise Linux 6 and Red Hat Enterprise Linux 7. Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section. 2. Relevant releases/architectures: Red Hat Enterprise Linux Client (v. 7) - x86_64 Red Hat Enterprise Linux Client Optional (v. 7) - x86_64 Red Hat Enterprise Linux ComputeNode (v. 7) - x86_64 Red Hat Enterprise Linux ComputeNode Optional (v. 7) - x86_64 Red Hat Enterprise Linux Desktop (v. 6) - i386, x86_64 Red Hat Enterprise Linux Desktop Optional (v. 6) - i386, x86_64 Red Hat Enterprise Linux HPC Node (v. 6) - x86_64 Red Hat Enterprise Linux HPC Node Optional (v. 6) - x86_64 Red Hat Enterprise Linux Server (v. 6) - i386, ppc64, s390x, x86_64 Red Hat Enterprise Linux Server (v. 7) - aarch64, ppc64, ppc64le, s390x, x86_64 Red Hat Enterprise Linux Server Optional (v. 6) - i386, ppc64, s390x, x86_64 Red Hat Enterprise Linux Server Optional (v. 7) - aarch64, ppc64, ppc64le, s390x, x86_64 Red Hat Enterprise Linux Workstation (v. 6) - i386, x86_64 Red Hat Enterprise Linux Workstation (v.7) - x86_64 Red Hat Enterprise Linux Workstation Optional (v. 6) - i386, x86_64 Red Hat Enterprise Linux Workstation Optional (v. 7) - x86_64 3. 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. Security Fix(es): * It was discovered that the sudo noexec restriction could have been bypassed if application run via sudo executed system(), popen(), or wordexp() C library functions with a user supplied argument. A local user permitted to run such application via sudo with noexec restriction could use these flaws to execute arbitrary commands with elevated privileges. (CVE-2016-7032, CVE-2016-7076) These issues were discovered by Florian Weimer (Red Hat). 4. Solution: For details on how to apply this update, which includes the changes described in this advisory, refer to: https://access.redhat.com/articles/11258 5. Bugs fixed (https://bugzilla.redhat.com/): 1372830 - CVE-2016-7032 sudo: noexec bypass via system() and popen() 1384982 - CVE-2016-7076 sudo: noexec bypass via wordexp() 6.

Fedora 24: 2016-112b333bdf Moderate: Sudo Noexec Bypass Threat

- update to 1.8.18p1 - fixes CVE-2016-7076. -------------------------------------------------------------------------------- Fedora Update Notification FEDORA-2016-112b333bdf 2016-11-11 17:07:42.816592 -------------------------------------------------------------------------------- Name : sudo Product : Fedora 24 Version : 1.8.18p1 Release : 1.fc24 URL : Summary : Allows restricted root access for specified usersDescription : 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: - update to 1.8.18p1 - fixes CVE-2016-7076 -------------------------------------------------------------------------------- References: [ 1 ] Bug #1384982 - CVE-2016-7076 sudo: noexec bypass via wordexp() https://bugzilla.redhat.com/show_bug.cgi?id=1384982 -------------------------------------------------------------------------------- This update can be installed with the "dnf" update program. Use su -c 'dnf upgrade sudo' at the command line. For more information, refer to the dnf documentation available at https://dnf.readthedocs.io/en/latest/command_ref.html All packages are signed with the Fedora Project GPG key.
