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"
