   An update that solves 5 vulnerabilities and has one errata
   is now available.

Description:

   This update for gtk2 provides the following fixes:

   These security issues were fixed:

   - CVE-2017-6312: Prevent integer overflow that allowed context-dependent
     attackers to cause a denial of service (segmentation fault and
     application crash) via a crafted image entry offset in an ICO file
     (bsc#1027026).
   - CVE-2017-6314: The make_available_at_least function allowed
     context-dependent attackers to cause a denial of service (infinite loop)
     via a large TIFF file (bsc#1027025).
   - CVE-2017-6313: Prevent integer underflow in the load_resources function
     that allowed context-dependent attackers to cause a denial of service
     (out-of-bounds read and program crash) via a crafted image entry size in
     an ICO file (bsc#1027024).
   - CVE-2017-2862: Prevent heap overflow in the
     gdk_pixbuf__jpeg_image_load_increment function. A specially crafted jpeg
     file could have caused a heap overflow resulting in remote code
     execution (bsc#1048289)
   - CVE-2017-2870: Prevent integer overflow in the tiff_image_parse
     functionality. A specially crafted tiff file could have caused a
     heap-overflow resulting in remote code execution (bsc#1048544).

   This non-security issue was fixed:

   - Prevent an infinite loop when a window is destroyed while traversed
     (bsc#1039465).
