Título:	RedHat Security Advisory RHSA-2010:0237
Resumen:	NOSUMMARY
Descripción:	Description: The remote host is missing updates announced in advisory RHSA-2010:0237. Sendmail is a very widely used Mail Transport Agent (MTA). MTAs deliver mail from one machine to another. Sendmail is not a client program, but rather a behind-the-scenes daemon that moves email over networks or the Internet to its final destination. The configuration of sendmail in Red Hat Enterprise Linux was found to not reject the localhost.localdomain domain name for email messages that come from external hosts. This could allow remote attackers to disguise spoofed messages. (CVE-2006-7176) A flaw was found in the way sendmail handled NUL characters in the CommonName field of X.509 certificates. An attacker able to get a carefully-crafted certificate signed by a trusted Certificate Authority could trick sendmail into accepting it by mistake, allowing the attacker to perform a man-in-the-middle attack or bypass intended client certificate authentication. (CVE-2009-4565) Note: The CVE-2009-4565 issue only affected configurations using TLS with certificate verification and CommonName checking enabled, which is not a typical configuration. Solution: All users of sendmail 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 http://rhn.redhat.com/errata/RHSA-2010-0237.html http://www.redhat.com/security/updates/classification/#low Risk factor : High CVSS Score: 7.5
