Bug(s): #642200
ID: 202007-40

Synopsis

A vulnerability was discovered in Thin which may allow local
attackers to kill arbitrary processes (denial of service).


Background

Thin is a small and fast Ruby web server.

Affected Packages

Package: www-servers/thin

Architectures: All supported architectures

Impact

A local attacker could cause denial of service by killing arbitrary
processes.


Workaround

There is no known workaround at this time.

Resolution

Gentoo has discontinued support for Thin. We recommend that users
unmerge Thin:
