Security fix: CVE-2015-3238
If the process executing pam_sm_authenticate or pam_sm_chauthtok method
of pam_unix is not privileged enough to check the password, e.g.
if selinux is enabled, the _unix_run_helper_binary function is called.
When a long enough password is supplied (16 pages or more, i.e. 65536+
bytes on a system with 4K pages), this helper function hangs
indefinitely, blocked in the write(2) call while writing to a blocking
pipe that has a limited capacity.
With this fix, the verifiable password length will be limited to
PAM_MAX_RESP_SIZE bytes (i.e. 512 bytes) for pam_exec and pam_unix.
* NEWS: Update
* configure.ac: Bump version
* modules/pam_exec/pam_exec.8.xml: document limitation of password length
* modules/pam_exec/pam_exec.c: limit password length to PAM_MAX_RESP_SIZE
* modules/pam_unix/pam_unix.8.xml: document limitation of password length

This change introduces pam_modutil_sanitize_helper_fds - a new function
that redirects standard descriptors and closes all other descriptors.
pam_modutil_sanitize_helper_fds supports three types of input and output
redirection:
- PAM_MODUTIL_IGNORE_FD: do not redirect at all.
- PAM_MODUTIL_PIPE_FD: redirect to a pipe. For stdin, it is implemented
by creating a pipe, closing its write end, and redirecting stdin to
its read end. Likewise, for stdout/stderr it is implemented by
creating a pipe, closing its read end, and redirecting to its write
end. Unlike stdin redirection, stdout/stderr redirection to a pipe
has a side effect that a process writing to such descriptor should be
prepared to handle SIGPIPE appropriately.
- PAM_MODUTIL_NULL_FD: redirect to /dev/null. For stdin, it is
implemented via PAM_MODUTIL_PIPE_FD because there is no functional
difference. For stdout/stderr, it is classic redirection to
/dev/null.
PAM_MODUTIL_PIPE_FD is usually more suitable due to linux kernel
security restrictions, but when the helper process might be writing to
the corresponding descriptor and termination of the helper process by
SIGPIPE is not desirable, one should choose PAM_MODUTIL_NULL_FD.
* libpam/pam_modutil_sanitize.c: New file.
* libpam/Makefile.am (libpam_la_SOURCES): Add it.
* libpam/include/security/pam_modutil.h (pam_modutil_redirect_fd,
pam_modutil_sanitize_helper_fds): New declarations.

There is no need to copy strings passed as arguments to execve,
the only potentially noticeable effect of using strdup/x_strdup
would be a malformed argument list in case of memory allocation error.
Also, x_strdup, being a thin wrapper around strdup, is of no benefit
when its argument is known to be non-NULL, and should not be used in
such cases.

instead of x_strdup, the latter is of no benefit in this case.

glibc's <sys/wait.h> starting with commit
http://sourceware.org/git/?p=glibc.git;a=commitdiff;h=glibc-2.15-231-gd94a467
does not include <sys/resource.h> for POSIX 2008 conformance reasons, so
when pam is being built with SELinux support enabled, pam_unix_passwd.c
uses getrlimit(2) and therefore should include <sys/resource.h> without
relying on other headers.
* modules/pam_unix/pam_unix_passwd.c: Include <sys/resource.h>.

In --enable-static-modules mode, it was not possible to use "pam_unix"
in PAM config files. Instead, different names had to be used for each
management group: pam_unix_auth, pam_unix_acct, pam_unix_passwd and
pam_unix_session. This change makes pam_unix configuration consistent
with other PAM modules.
* README: Remove the paragraph describing pam_unix distinctions in
--enable-static-modules mode.

_pam_unix_auth_modstruct, _pam_unix_passwd_modstruct,
