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).
