Type Arbitrary code execution

Description

When libtiff's tiff2rgba handles a maliciously-crafted tiff file(width= 8388640, height=31) an illegal write happens. This vulnerability exists in the function cvt_by_strip (and cvt_by_tile ) due to an improper buffer allocation. An attacker may control the write address and/or value to result in denial-of-service or arbitrary code execution.
