An improper input sanitization flaw was found in the way feh,
the versatile and fast image viewer using imlib2, escaped URLs
to remote image files, to be reloaded. If a remote attacker could
trick the local user into opening a specially-crafted URL (where
that URL led to a valid file), it could lead to arbitrary code
execution with the privileges of the user running feh.
