Format string vulnerability in the windowerror 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.

XScreenSaver in Sun Solaris 10 and OpenSolaris before snv109, and Solaris 8 and 9 with GNOME 2.0 or 2.0.2, allows physically proximate attackers to obtain sensitive information by reading popup windows, which are displayed even when the screen is locked, as demonstrated by Thunderbird new-mail notifications.

The gdk-pixbuf configuration in Mozilla Firefox before 43.0 on Linux GNOME platforms incorrectly enables the JasPer decoder, which allows remote attackers to cause a denial of service or possibly have unspecified other impact via a crafted JPEG 2000 image.

The gdk-pixbuf configuration in Mozilla Firefox before 43.0 on Linux GNOME platforms incorrectly enables the TGA decoder, which allows remote attackers to cause a denial of service (heap-based buffer overflow) via a crafted Truevision TGA image.
