A flaw was found in GNOME Shell's remote search integration. When rendering an icon supplied by a remote search provider over D-Bus, the icon's declared width, height, and row stride are passed to Shell.util_create_pixbuf_from_data() without validating that this geometry is consistent with the actual size of the supplied data buffer. A malicious or compromised search provider can advertise icon dimensions larger than its actual buffer, causing GNOME Shell to read past the end of the buffer when constructing the pixbuf for display. This out-of-bounds read can crash the GNOME Shell process, disrupting the user's session, and could potentially expose adjacent heap memory contents through the rendered icon.
