Format string vulnerability in the window_error function in yelp-window.c in yelp in Gnome after 2.19.90 and before 2.24 allows remote attackers to execute arbitrary code via format string specifiers in an invalid URI on the command line, as demonstrated by use of yelp within (1) man or (2) ghelp URI handlers in Firefox, Evolution, and unspecified other programs.
