DESCRIPTION:
Gentoo has issued an update for feh. This fixes a weakness and a
security issue, which can be exploited by malicious, local users to
perform certain actions with escalated privileges and by malicious
people to potentially compromise a user's system.

For more information:
SA43221

1) The weakness is caused due to an error in the
"feh_http_load_image()" function (src/imlib.c) when using the
"--wget-timestamp" command line option. This can be exploited to
inject arbitrary shell commands into an URL passed as command line
argument, which will be executed, if a user is tricked into opening a
specially crafted URL using the "--wget-timestamp" command line
option.

SOLUTION:
Update to "media-gfx/feh-1.12" or later.

PROVIDED AND/OR DISCOVERED BY:
1) Disclosed in a GIT commit.
