The remote Mandriva Linux host is missing one or more security updates.


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.
