Synopsis
========

A vulnerability in mini_httpd could allow remote attackers to execute
arbitrary code.

Background
==========

mini_httpd is a small webserver with optional SSL and IPv6 support.

Affected packages
=================

    -------------------------------------------------------------------
     Package              /     Vulnerable     /            Unaffected
    -------------------------------------------------------------------
  1  www-servers/mini_httpd       *<= 1.19                 Vulnerable!
    -------------------------------------------------------------------
     NOTE: Certain packages are still vulnerable. Users should migrate
           to another package if one is available or wait for the
           existing packages to be marked stable by their
           architecture maintainers.

Description
===========

mini_httpd does not properly check for shell escapes when parsing HTTP
requests.

Impact
======

A remote attacker could send specially crafted HTTP requests, possibly
resulting in execution of arbitrary code with the privileges of the
process, or allowing for overwriting of files.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

Gentoo discontinued support for mini_httpd. We recommend that users
unmerge mini_httpd:

  # emerge --unmerge "www-servers/mini_httpd"
