LibGD 2.2.4 release

LibGD team is proud to announce the 2.2.4 release of libgd.

Security related fixes: This flaw is caused by loading data from external sources (file, custom ctx, etc) and are hard to validate before calling libgd APIs:

  • gdImageCreate() doesn't check for oversized images and as such is prone to DoS vulnerabilities. (CVE-2016-9317)
  • double-free in gdImageWebPtr() (CVE-2016-6912)
  • potential unsigned underflow in gd_interpolation.c (CVE-2016-10166)
  • DOS vulnerability in gdImageCreateFromGd2Ctx() (CVE-2016-10167)
  • Signed Integer Overflow gd_io.c (CVE-2016-10168)
