Release version 1.2.1
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
* modules/pam_unix/pam_unix_passwd.c: limit password length
* modules/pam_unix/passverify.c: Likewise
* modules/pam_unix/passverify.h: Likewise
* modules/pam_unix/support.c: Likewise
