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.
A NULL pointer dereference occurs when the application dereferences a pointer that it expects to be valid, but is NULL, typically causing a crash or exit.
