Opening a maliciously crafted PICT image may lead to an unexpected application termination or arbitrary code execution
The specific flaw exists when the application parses a malformed .PICT image. While decoding a tag 0x77 in the image, the application misuses a 16-bit length when allocating tag data. When copying tag data into this buffer, a heap overflow occurs. This can lead to code execution under the context of the current user.
