+Subject: [PATCH] * libtiff/tif_getimage.c: fix out-of-bound reads in
+ TIFFRGBAImage interface in case of unsupported values of
+ SamplesPerPixel/ExtraSamples for LogLUV / CIELab. Add explicit call to
+ TIFFRGBAImageOK() in TIFFRGBAImageBegin(). Fix CVE-2015-8665 reported by
+ limingxing and CVE-2015-8683 reported by zzf of Alibaba.
