Fedora 24: gd Security Update 2017-2717b02630

January 24, 2017

## Version 2.2.4 - 2017-01-18 ### Security - gdImageCreate() doesn't check for oversized images and as such is prone to DoS vulnerabilities

Summary

The gd graphics library allows your code to quickly draw images

complete with lines, arcs, text, multiple colors, cut and paste from

other images, and flood fills, and to write out the result as a PNG or

JPEG file. This is particularly useful in Web applications, where PNG

and JPEG are two of the formats accepted for inline images by most

browsers. Note that gd is not a paint program.
