Notes
[wheezy] - graphicsmagick <no-dsa> (Not possible to trigger with presented test case)
http://hg.code.sf.net/p/graphicsmagick/code/rev/e8086faa52d0
https://sourceforge.net/p/graphicsmagick/bugs/519/
The wheezy version gives an assert before the vulnerability can be triggered. Due to this
the severity of the wheezy version is low even though the vulnerable code is still present.
The patch is trivial so it may be worth fixing in combination with some other fix.
