The Gnumeric spreadsheet is a versatile application developed as part of the GNOME Office project.
James Vega reported an untrusted search path vulnerability in the GObject Python interpreter wrapper in Gnumeric.
A local attacker could entice a user to run Gnumeric from a directory containing a specially crafted python module, resulting in the execution of arbitrary code with the privileges of the user running Gnumeric.
Do not run "gnumeric" from untrusted working directories.
All Gnumeric users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=app-office/gnumeric-1.8.4-r1"
