Background ========== Logcheck mails anomalies in the system logfiles to the administrator. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 app-admin/logcheck <= 1.3.23 Vulnerable! Description =========== The pkg_postinst phase of the Logcheck ebuilds recursively chown the /etc/logcheck and /var/lib/logcheck directories. If the logcheck adds hardlinks to other files in these directories, the chown call will follow the link and transfer ownership of any file to the logcheck user. Impact ====== A local attacker with access to the logcheck user could escalate to root privileges. Workaround ========== There is no known workaround at this time. Resolution ========== Gentoo has discontinued support for Logcheck. We recommend that users remove it: # emerge --ask --depclean "app-admin/logcheck" References ========== [ 1 ] CVE-2017-20148 https://nvd.nist.gov/vuln/detail/CVE-2017-20148 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: https://security.gentoo.org/glsa/202209-10 Concerns? ========= Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users' machines is of utmost importance to us.
