What is CVE-2016-9448?

The TIFFFetchNormalTag function in LibTiff version 4.0.6 is vulnerable to a denial of service caused by a NULL pointer dereference, resulting in a program crash. This vulnerability arises when attackers manipulate the tags TIFF_SETGET_C16ASCII or TIFF_SETGET_C32_ASCII, prompting the function to access empty byte arrays. It is a regression of a previous issue, indicating a failure in properly addressing prior vulnerabilities, making systems relying on this library susceptible to exploitation.
