Synopsis: Low: sendmail security and bug fix update
Issue date: 2010-03-30
CVE Names: CVE-2006-7176 CVE-2009-4565
The configuration of sendmail in Scientific 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.
This update also fixes the following bugs:
* sendmail was unable to parse files specified by the ServiceSwitchFile
option which used a colon as a separator. (BZ#512871)
* sendmail incorrectly returned a zero exit code when free space was
low. (BZ#299951)
* the sendmail manual page had a blank space between the -qG option and
parameter. (BZ#250552)
* the comments in the sendmail.mc file specified the wrong path to SSL
certificates. (BZ#244012)
* the sendmail packages did not provide the MTA capability. (BZ#494408)
