A flaw was found in libtiff. The get_histogram function in file/tiffmedian.c exhibits a use-after-free condition when processing a specially crafted file, allowing a local attacker to trigger memory corruption. This manipulation results in a use-after-free vulnerability, and can lead to a denial of service.
