CVE-1999-1158

This exploit targets a buffer overflow vulnerability in the Solaris 2.4 and 2.5 passwd program, using shellcode to achieve remote code execution. The exploit constructs a malicious buffer with NOP sleds and shellcode to overwrite the return address and execute arbitrary code.

This exploit targets a buffer overflow in Pluggable Authentication Modules (PAM) and unix_scheme on Solaris 2.5.(1). It uses a stack-based overflow via the passwd program to execute shellcode, potentially granting root access.
