readelf in GNU Binutils 2.28 has a use-after-free (specifically read-after-free) error while processing multiple, relocated sections in an MSP430 binary. This is caused by mishandling of an invalid symbol index, and mishandling of state across invocations.

Weakness

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 Any operations using the original pointer are no longer valid because the memory “belongs” to the code that operates on the new pointer.
