Title: Blam: User-assisted execution of arbitrary code
Date: January 27, 2008
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"
References
==========
