Creolabs Gravity Version: 1.0 Use-After-Free Possible code execution. An example of a Heap-Use-After-Free after the sublexer pointer has been freed. Line 542 of gravity_lexer.c. lexer is being used to access a variable but lexer has already been freed, creating a Heap Use-After-Free condition.
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 Any operations using the original pointer are no longer valid because the memory “belongs” to the code that operates on the new pointer.
