Description Laura Pardo 2018-07-27 18:06:38 EDT

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