Synopsis
========

Gentoo's tenshi ebuild is vulnerable to privilege escalation due to the
way pid files are handled.

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
