Summary
Two heap-based buffer overflow vulnerabilities exist in the TIFF parser functionality of Accusoft ImageGear 19.10. A specially-crafted file can lead to a heap buffer overflow. An attacker can provide a malicious file to trigger these vulnerabilities.This heap-based buffer oveflow takes place trying to copy the first 12 bits from local variable.
