An issue was discovered in Adobe Acrobat and Reader: 2017.012.20098 and earlier versions, 2017.011.30066 and earlier versions, 2015.006.30355 and earlier versions, and 11.0.22 and earlier versions. The vulnerability is caused by a buffer access with an incorrect length value in TIFF parsing during XPS conversion. Crafted TIFF image input causes a mismatch between allocated buffer size and the access allowed by the computation. If an attacker can adequately control the accessible memory then this vulnerability can be leveraged to achieve arbitrary code execution.
The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.
