Test ID:1.3.6.1.4.1.25623.1.0.67161
Category:Red Hat Local Security Checks
Title:RedHat Security Advisory RHSA-2010:0258
Summary:NOSUMMARY
Description:Description:
The remote host is missing updates announced in
advisory RHSA-2010:0258.

The pam_krb5 module allows Pluggable Authentication Modules (PAM) aware
applications to use Kerberos to verify user identities by obtaining user
credentials at log in time.

A flaw was found in pam_krb5. In some non-default configurations
(specifically, those where pam_krb5 would be the first module to prompt for
a password), the text of the password prompt varied based on whether or not
the username provided was a username known to the system. A remote attacker
could use this flaw to recognize valid usernames, which would aid a
dictionary-based password guess attack. (CVE-2009-1384)

Solution:
Users of pam_krb5 are advised to upgrade to these updated packages, which
resolve these issues.

Please note that this update is available via
Red Hat Network. To use Red Hat Network, launch the Red
Hat Update Agent with the following command: up2date
