Multiple vulnerabilities in libtiff before 3.8.1 allow context-dependent
attackers to cause a denial of service via a TIFF image that triggers
errors in (1) the TIFFFetchAnyArray function in (a) tif_dirread.c; (2)
certain “codec cleanup methods” in (b) tif_lzw.c, © tif_pixarlog.c, and
(d) tif_zip.c; (3) and improper restoration of setfield and getfield
methods in cleanup functions within (e) tif_jpeg.c, tif_pixarlog.c, (f)
tif_fax3.c, and tif_zip.c.
