"This update for openexr fixes the following issues :

  - CVE-2017-9110: In OpenEXR, an invalid read of size 2 in
    the hufDecode function in ImfHuf.cpp could cause the
    application to crash. (bsc#1040107)

  - CVE-2017-9114: In OpenEXR, an invalid read of size 1 in
    the refill function in ImfFastHuf.cpp could cause the
    application to crash. (bsc#1040114)

  - CVE-2017-12596: In OpenEXR, a crafted image causes a
    heap-based buffer over-read in the hufDecode function in
    IlmImf/ImfHuf.cpp during exrmaketiled execution; it
    could have resulted in denial of service or possibly
    unspecified other impact. (bsc#1052522)

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."
