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"


References

CVE-2005-4790
