2017-03-23Fix double-free/OOB-write while receiving IPC dataTobias Stoeckmann-1/+1
If a malicious client pretends to be the E17 window manager, it is possible to trigger an out of boundary heap write while receiving an IPC message. The length of the already received message is stored in an unsigned short, which overflows after receiving 64 KB of data. It's comparably small amount of data and therefore achievable for an attacker. When len overflows, realloc() will either be called with a small value and therefore chars will be appended out of bounds, or len + 1 will be exactly 0, in which case realloc() behaves like free(). This could be abused for a later double-free attack as it's even possible to overwrite the free information -- but this depends on the malloc implementation.

2016-05-01src/wallpaper.c: free up some data allocated by X.Daniel Lockyer-0/+7
The if statements are needed because we cannot pass a NULL pointer to XFree.

2015-06-22support background setter for specific screenJames Knight-20/+77
The following adds the ability, when using `feh` as a background setter, to use a specific Xinerama screen to render a provided image. Along with the provided '--bg-*' option, the '--xinerama-index' argument will be used to identify the index of the detected Xinerama screen to use.

2015-06-22ensure fehbg is free'edJames Knight-1/+2
The 'fehbg' variable can be allocated whether or not the user wishes to generated a fehbg file. Ensure the variable is free'ed before we return. Signed-off-by: James Knight <james.d.knight@live.com>

2013-09-26Support geometry in --bg-max and --bg-centerJoel Bradshaw-4/+34
Overloads the --geometry option for wallpaper setting Currently only supports the two options that result in black borders, --bg-max and --bg-center. For both, if a geometry offset is specified (w/h is ignored), the image will be offset the specified pixels from the screen edge Left side for + numbers, right side for -. +/-0 will align at the edge of the screen.
2012-12-04--bg-max: Respect --image-bg settingDaniel Friesel-6/+3
2012-10-17Add --image-bg option for wallpaper borderRob Cornish-3/+12
Previously feh would set a black background around wallpaper images, with no option to change. This commit extends the functionality offered by the --image-bg option, which is available for regular image viewing, to centered and max'ed feh backgrounds. Essentially, this means a white border can now be chosen in addition to a black one.
