An issue in file() was introduced in commit 9611f31313a93aa036389c5f3b15eea53510d4d1 (Oct 2016) lets an attacker overwrite a fixed 20 bytes stack buffer with a specially crafted .notes section in an ELF binary. This was fixed in commit 35c94dc6acc418f1ad7f6241a6680e5327495793 (Aug 2017).
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.
