Descriptions

libtiff 4.5.0 is vulnerable to Buffer Overflow in uv_encode() when libtiff reads a corrupted little-endian TIFF file and specifies the output to be big-endian.

A flaw was found in libtiff. A specially crafted tiff file can lead to a segmentation fault due to an out-of-bounds read in the uv_encode function in libtiff/tif_luv.c, resulting in a denial of service.
