CVE-2015-8877

Published: 21 May 2016

The gdImageScaleTwoPass function in gd_interpolation.c in the GD Graphics Library (aka libgd) before 2.2.0, as used in PHP before 5.6.12, uses inconsistent allocate and free approaches, which allows remote attackers to cause a denial of service (memory consumption) via a crafted call, as demonstrated by a call to the PHP imagescale function.

2.1.0-3, as shipped in Trusty, has quite a different implementation
for gdImageScaleTwoPass() but I believe it is still affected
