A use-after-free vulnerability exists in the Figure stream parsing functionality of Ichitaro 2023 1.0.1.59372. A specially crafted document can cause memory corruption, resulting in arbitrary code execution. Victim would need to open a malicious file to trigger this vulnerability.
The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory “belongs” to the code that operates on the new pointer.
