Detail
Problem Description: An update for sudo is now available for Red Hat Enterprise Linux 7. Red Hat Product Security has rated this update as having a security impact of Low. 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 Server (v. 7) - aarch64, ppc64, ppc64le, s390x, x86_64 Red Hat Enterprise Linux Server Optional (v. 7) - aarch64, ppc64, ppc64le, s390x, x86_64 Red Hat Enterprise Linux Workstation (v. 7) - 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 default sudo configuration preserved the value of INPUTRC from the user's environment, which could lead to information disclosure. A local user with sudo access to a restricted program that uses readline could use this flaw to read content from specially formatted files with elevated privileges provided by sudo. (CVE-2016-7091) Note: With this update, INPUTRC was removed from the env_keep list in /etc/sudoers to avoid having sudo preserve the value of this variable when invoking privileged commands. Red Hat would like to thank Grisha Levit for reporting this issue. Additional Changes: For detailed information on changes in this release, see the Red Hat Enterprise Linux 7.3 Release Notes linked from the References section. 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/): 1196451 - default requiretty is problematic and breaks valid usage 1261998 - visudo accept non valid content 1268958 - sudo - cmnd_no_wait can cause child processes to ignore SIGPIPE 1334360 - sudo option mail_no_user doesn't work 1339935 - CVE-2016-7091 sudo: Possible info leak via INPUTRC 1350828 - [RHEL7] visudo ignores -q flag |
