objdump in GNU Binutils 2.28 is vulnerable to multiple heap-based buffer over-reads (of size 1 and size 8) while handling corrupt STABS enum type strings in a crafted object file, leading to program crash.
The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.
