A buffer overflow vulnerability exists in libtiff version 4.5.0 within the uv_encode() function. This occurs when libtiff processes a corrupted little-endian TIFF file and the output is specified as big-endian.

A buffer overflow vulnerability exists in libtiff version 4.5.0 due to incorrect buffer size updating after the rotateImage() function in the tiffcrop tool. This flaw can cause a heap-buffer-overflow and lead to a segmentation fault (SEGV).
