Tomboy is a desktop note-taking application.
Tomboy places a zero-length directory name in the LD_LIBRARY_PATH, which might result in the current working directory (.) to be included when searching for dynamically linked libraries.
NOTE: This vulnerability exists due to an incomplete fix for CVE-2005-4790 (GLSA 200711-12).
A local attacker could gain escalated privileges via a specially crafted shared library.
There is no known workaround at this time.
All Tomboy users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=app-misc/tomboy-1.4.2-r1"
NOTE: This is a legacy GLSA. Updates for all affected architectures are available since March 02, 2011. It is likely that your system is already no longer affected by this issue.
