"A security vulnerability has been identified and fixed in pam :

Integer signedness error in the _pam_StrTok function in
libpam/pam_misc.c in Linux-PAM (aka pam) 1.0.3 and earlier, when a
configuration file contains non-ASCII usernames, might allow remote
attackers to cause a denial of service, and might allow remote
authenticated users to obtain login access with a different user's
non-ASCII username, via a login attempt (CVE-2009-0887).

The updated packages have been patched to prevent this.

Additionally some development packages were missing that are required
to build pam for CS4, these are also provided with this update."
