SUSE-SU-2018:2470-1

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).
