CVE-2003-0102

This exploit leverages a stack overflow in the `file` program (CVE-2003-0102) to execute arbitrary shellcode. It crafts a malicious ELF file that, when processed by `file`, triggers the overflow and executes a payload that copies `/bin/sh` to `/tmp/.sh` with SUID permissions.

This exploit leverages a stack overflow in the `file` utility (versions <= 3.39) by manipulating the ELF header's `e_shentsize` field to trigger a buffer overflow, allowing arbitrary code execution. The shellcode is placed in the file's initial bytes, exploiting the `HOWMANY` read operation to ensure reliable execution.
