Blam doesn't properly handle environment variables, potentially allowing a
local attacker to execute arbitrary code.
Blam is an RSS and Atom feed reader for GNOME written in C#.
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.
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
Do not run Blam from an untrusted working directory.
All Blam users should upgrade to the latest version:
