Description Laura Pardo 2018-07-27 18:02:00 EDT

An issue was discovered in LibTIFF 4.0.9. A buffer overflow vulnerability can occur via an invalid or empty tif argument to TIFFRGBAImageOK in tif_getimage.c, and it can be exploited (at a minimum) via the following high-level library API functions: TIFFReadRGBAImage, TIFFRGBAImageOK, and TIFFRGBAImageBegin.
