passwd

[Sunil Sunder Raj]

Hi,
After tracing the passwd command I found these files being referred by the 
command.

/sbin/passwd
/var/run/ld-elf.so.hints
/usr/lib/libkadm.so.3
/usr/lib/libkrb.so.3
/usr/lib/libcrypto.so.1
/usr/lib/libcrypt.so.2
/usr/lib/librpcsvc.so.2
/usr/lib/libcom_err.so.2
/usr/lib/libutil.so.3
/usr/lib/libc.so.4
/usr/lib/libcrypt.so.2
/etc/malloc.conf
/etc/spwd.db
/etc/auth.conf
/dev/tty
/dev/urandom
/etc/master.passwd
/etc/localtime
/etc/passwd
/var/run/log


and access to the users' home directory.

Regards
SSR
