A heap-based buffer overflow vulnerability exists in the PSD read_icc_icCurve_data functionality of Accusoft ImageGear 19.9. A specially crafted malformed file can lead to an integer overflow that, in turn, leads to a heap buffer overflow. An attacker can provide a malicious file to trigger this vulnerability.
A heap overflow condition is a buffer overflow, where the buffer that can be overwritten is allocated in the heap portion of memory, generally meaning that the buffer was allocated using a routine such as malloc().
The product writes data past the end, or before the beginning, of the intended buffer.
