An integer overflow exists in the "HyperLinkFrame" stream parser of Ichitaro 2023 1.0.1.59372. A specially crafted document can cause the parser to make an under-sized allocation, which can later allow for memory corruption, potentially resulting in arbitrary code execution. An attacker can provide a malicious file to trigger this vulnerability.
The product performs a calculation that can produce an integer overflow or wraparound when the logic assumes that the resulting value will always be larger than the original value. This occurs when an integer value is incremented to a value that is too large to store in the associated representation. When this occurs, the value may become a very small or negative number.
