Severity: Normal 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"
