An issue has been found in function Gfx::doShowText in PDF2JSON 0.70 that allows attackers to cause a Denial of Service due to an Use After Free .
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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.
