Bug #73161 imagecreatefromgd2() may leak memory
Submitted: 2016-09-24 10:05 UTC Modified: 2016-09-24 10:05 UTC
From: cmb@php.net Assigned: cmb
Status: Closed Package: GD related
PHP Version: 5.6Git-2016-09-24 (Git) OS: *
Private report: No CVE-ID:
 [2016-09-24 10:05 UTC] cmb@php.net
Description:
------------
If the color header of a GD2 image can't be read,
gdimagecreatefromgd2() fails to free a t_chunk_info structure,
causing a memory leak.

I don't think this is a security issue, as the GD2 format is not
supposed to be used for production purposes anyway, see
<https://libgd.github.io/release-2.2.2.html>.

FTR: this issue has been fixed as of libgd 2.1.0.
