Description Laura Pardo 2018-07-27 21:58:39 UTC 
An issue was discovered in LibTIFF 4.0.9. A buffer overflow can occur via an empty fmt argument to unixErrorHandler in tif_unix.c, and it can be exploited (at a minimum) via the following high-level library API functions: TIFFClientOpen, TIFFFdOpen, TIFFRawStripSize, TIFFCheckTile, TIFFComputeStrip, TIFFReadRawTile, TIFFUnRegisterCODEC, and TIFFWriteEncodedTile.
