Library with common API for various GNOME modules.
A vulnerability was discovered in the GNOME desktop library which allows an attacker to escape the sandbox.
A local attacker could possibly bypass sandbox protection.
There is no known workaround at this time.
All GNOME desktop library users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose
">=gnome-base/gnome-desktop-3.30.2.3"
