Libtiff: null pointer dereference in tif_dirinfo.c
A null pointer dereference flaw was found in Libtiff via `tif_dirinfo.c`. This issue may allow an attacker to trigger memory allocation failures through certain means, such as restricting the heap space size or injecting faults, causing a segmentation fault. This can cause an application crash, eventually leading to a denial of service.
