Critical Buffer Overflow in ELF Parser: How a Missing Bounds Check Almost Became a Heap Exploit

A critical out-of-bounds memory vulnerability was discovered and patched in `utils/symbol-rawelf.c`, where two separate `memcpy` calls lacked proper bounds validation when processing ELF binary files. Without these checks, a maliciously crafted ELF file could trigger an out-of-bounds read or heap overflow, potentially leading to remote code execution or memory corruption. This post breaks down how the vulnerability works, how it was fixed, and what every C developer should know about safe memory
