Synopsis ========
A vulnerability in yelp can lead to the execution of arbitrary code when opening a URI, for example through Firefox.
Background ==========
yelp is the default help browser for GNOME.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 gnome-extra/yelp < 2.22.1-r2 >= 2.22.1-r2 *>= 2.20.0-r1
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"
