Tomboy is a GTK-based desktop note-taking application written in C# and the Mono C#.
Jan Oravec reported that the "/usr/bin/tomboy" script sets the "LD_LIBRARY_PATH" environment variable incorrectly, which might result in the current working directory (.) to be included when searching for dynamically linked libraries of the Mono Runtime application.
A local attacker could entice a user into running Tomboy in a directory containing a specially crafted library file to execute arbitrary code with the privileges of the user running Tomboy.
Do not run Tomboy from an untrusted working directory.
All Tomboy users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=app-misc/tomboy-0.8.1-r1"
