Synopsis
=======
A buffer overflow in libproxy might allow remote attackers to execute
arbitrary code.

Background
=========
libproxy is a library for automatic proxy configuration management.

Affected packages
================
    -------------------------------------------------------------------
     Package              /     Vulnerable     /            Unaffected
    -------------------------------------------------------------------
  1  net-libs/libproxy            < 0.4.10                  >= 0.4.10 

Description
==========
A boundary error when processing the proxy.pac file could cause a
stack-based buffer overflow.

Impact
=====
A man-in-the-middle attacker could provide a specially crafted
proxy.pac file on a remote server, possibly resulting in execution of
arbitrary code with the privileges of the process or a Denial of
Service condition.

Workaround
=========
There is no known workaround at this time.

Resolution
=========
All libproxy users should upgrade to the latest version:

  # emerge --sync
  # emerge --ask --oneshot --verbose ">=net-libs/libproxy-0.4.10"
