Description
Aaron Grattafiori reported a format string vulnerability in the window_error() function in yelp-window.c.
Impact
A remote attacker can entice a user to open specially crafted "man:" or "ghelp:" URIs in yelp, or an application using yelp such as Firefox or Evolution, and execute arbitrary code with the privileges of that user.
Workaround
There is no known workaround at this time.
Resolution
All yelp users running GNOME 2.22 should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=gnome-extra/yelp-2.22.1-r2"
All yelp users running GNOME 2.20 should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=gnome-extra/yelp-2.20.0-r1"
