Description Laura Pardo 2018-05-11 21:39:14 UTC 
A flaw was found in LibTIFF 3.8.2TIFF. The ClientOpen function in tif_unix.c file has memory leaks which allow local attackers to cause a denial of service (memory consumption) via crafted file.

Comment 5 Riccardo Schirone 2018-07-06 09:32:38 UTC 
In bmp2tiff tool a file is opened for writing with TIFFOpen, but when the iBitCount header value is wrong, the tool exits without closing the file.
