CVE-1999-0038

This exploit targets a buffer overflow vulnerability in xlock (CVE-1999-0038) to achieve local privilege escalation. It constructs a malicious environment variable and overflows the buffer to execute arbitrary shellcode, potentially granting root access.

This is a classic stack-based buffer overflow exploit for xlock, leveraging a vulnerable command-line argument to overwrite the return address and execute arbitrary shellcode. The exploit targets a suid root binary to achieve local privilege escalation.
