An exploitable heap overflow vulnerability exists in the image rendering functionality of Poppler 0.53.0. A specifically crafted PDF can cause an overly large number of color components during image rendering, resulting in heap corruption. An attacker controlled PDF file can be used to trigger this vulnerability.
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.
