Synopsis
=======
A vulnerability potentially allowing remote execution of arbitrary code
has been discovered in the neon library.

Background
=========
neon provides an HTTP and WebDAV client library.

Affected packages
================
    -------------------------------------------------------------------
     Package        /   Vulnerable   /                      Unaffected
    -------------------------------------------------------------------
  1  net-misc/neon       <= 0.24.5                           >= 0.24.6

Description
==========
Stefan Esser discovered a vulnerability in the code of the neon library
: if a malicious date string is passed to the ne_rfc1036_parse()
function, it can trigger a string overflow into static heap variables.

Impact
=====
Depending on the application linked against libneon and when connected
to a malicious WebDAV server, this vulnerability could allow execution
of arbitrary code with the rights of the user running that application.

Workaround
=========
There is no known workaround at this time. All users are advised to
upgrade to the latest available version of neon.

Resolution
=========
All users of neon should upgrade to the latest stable version:

    # emerge sync

    # emerge -pv ">=net-misc/neon-0.24.6"
    # emerge ">=net-misc/neon-0.24.6"
