"This update for gd fixes the following security issues :

  - CVE-2016-9317: The gdImageCreate function in the GD
    Graphics Library (aka libgd) allowed remote attackers to
    cause a denial of service (system hang) via an oversized
    image. (bsc#1022283)

  - CVE-2016-10167: A denial of service problem in
    gdImageCreateFromGd2Ctx() could lead to libgd running
    out of memory even on small files. (bsc#1022264)

  - CVE-2016-10168: A signed integer overflow in the GD
    Graphics Library (aka libgd) could lead to memory
    corruption (bsc#1022265)

Note that Tenable Network Security has extracted the preceding
description block directly from the SUSE security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."
