Overview
Affected versions of this package are vulnerable to Out-of-bounds Write in the TIFF CCITT Group 3 (T4) encoding process. An attacker can cause memory corruption and terminate the process by providing specially crafted 1-bit image data with narrow width and a large number of rows, leading to writes beyond the allocated output buffer. This is only exploitable if the application encodes 1-bit TIFF images using the CcittGroup3Fax compression, either by explicit encoder configuration or by re-encoding attacker-supplied TIFFs that retain this metadata.
