Background ========== A log monitoring program, designed to watch one or more log files for lines matching user defined regular expressions and report on the matches. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 app-admin/tenshi < 0.17 >= 0.17 Description =========== It was discovered that the tenshi ebuild creates a tenshi.pid file after dropping privileges to a non-root account. Impact ====== A local attacker could escalate privileges to root or kill arbitrary processes. Workaround ========== There is no known workaround at this time. Resolution ========== All tenshi users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=app-admin/tenshi-0.17" References ========== [ 1 ] CVE-2017-11746 https://nvd.nist.gov/vuln/detail/CVE-2017-11746 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: https://security.gentoo.org/glsa/201804-18 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.
