"value": "A vulnerability classified as problematic was found in libtiff 4.6.0. This vulnerability affects the function PS_Lvl2page of the file tools/tiff2ps.c of the component tiff2ps. The manipulation leads to null pointer dereference. It is possible to launch the attack on the local host. The complexity of an attack is rather high. The exploitation appears to be difficult. The exploit has been disclosed to the public and may be used. The name of the patch is 6ba36f159fd396ad11bf6b7874554197736ecc8b. It is recommended to apply a patch to fix this issue. One of the maintainers explains, that \"[t]his error only occurs if DEFER_STRILE_LOAD (defer-strile-load:BOOL=ON) or TIFFOpen( .. \"rD\") option is used.\""

Mitigation MIT-56
Implementation
For any pointers that could have been modified or provided from a function that can return NULL, check the pointer for NULL before use. When working with a multithreaded or otherwise asynchronous environment, ensure that proper locking APIs are used to lock before the check, and unlock when it has finished [REF-1484].
Mitigation
Requirements
Select a programming language that is not susceptible to these issues.
Mitigation
Implementation
Check the results of all functions that return a value and verify that the value is non-null before acting upon it.
Mitigation
Architecture and Design
Identify all variables and data stores that receive information from external sources, and apply input validation to make sure that they are only initialized to expected values.
Mitigation
Implementation
Explicitly initialize all variables and other data stores, either during declaration or just before the first usage.
No CAPEC attack patterns related to this CWE.
