Description Adam Mariš 2017-01-31 09:37:45 EST 
The gdImageCreate function in the GD Graphics Library (aka libgd) before 2.2.4 allows remote attackers to cause a denial of service (system hang) via an oversized image.

Upstream patch:

There has been no movement on this issue for four months. Is this going to be worked on?

The previous upstream patch described in comment #0 just adds whitespaces to the code. It seems like the actual patch is at:

https://github.com/libgd/libgd/commit/c3cf674cb444696a36f720f785878b41225af063#diff-2ebe418bf93ac39773a117e4b38fe86a
