Gentoo Linux Security Advisory
Title: Tomboy: User-assisted execution of arbitrary code (GLSA 200711-12)
Severity: normal
Exploitable: local
Date: November 08, 2007
Bug(s): #189249
ID: 200711-12
Synopsis
Tomboy doesn't properly handle environment variables, potentially allowing a local attacker to execute arbitrary code.
Background
Tomboy is a GTK-based desktop note-taking application written in C# and the Mono C#.
Affected Packages
Package: app-misc/tomboy
Vulnerable: < 0.8.1-r1
Unaffected: >= 0.8.1-r1
Architectures: All supported architectures
Description
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.
Impact
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.
Workaround
Do not run Tomboy from an untrusted working directory.
Resolution
All Tomboy users should upgrade to the latest version: Code: | # emerge --sync
# emerge --ask --oneshot --verbose ">=app-misc/tomboy-0.8.1-r1" |
