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.
Bugs
Notes
| Author | Note |
|---|---|
| mdeslaur | php uses the system libgd2 |
| tyhicks | 2.1.0-3, as shipped in Trusty, has quite a different implementation for gdImageScaleTwoPass() but I believe it is still affected |
