      Bugs: #199841
        ID: 200801-14

Synopsis
=======
Blam doesn't properly handle environment variables, potentially
allowing a local attacker to execute arbitrary code.

Background
=========
Blam is an RSS and Atom feed reader for GNOME written in C#.

Affected packages
================
    -------------------------------------------------------------------
     Package        /  Vulnerable  /                        Unaffected
    -------------------------------------------------------------------
  1  net-news/blam       < 1.8.4                              >= 1.8.4

Description
==========
The "/usr/bin/blam" script sets the "LD_LIBRARY_PATH" environment
variable incorrectly, which might result in the current working
directory (.) being included when searching for dynamically linked
libraries of the Mono Runtime application.

Impact
=====
A local attacker could entice a user to run Blam in a directory
containing a specially crafted library file which could result in the
execution of arbitrary code with the privileges of the user running
Blam.

Workaround
=========
Do not run Blam from an untrusted working directory.

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

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=net-news/blam-1.8.4"
