Common Vulnerabilities and Exposures assigned an identifier CVE-2009-3767 to the following vulnerability: libraries/libldap/tls_o.c in OpenLDAP, when OpenSSL is used, does not properly handle a '\0' character in a domain name in the subject's Common Name (CN) field of an X.509 certificate, which allows man-in-the-middle attackers to spoof arbitrary SSL servers via a crafted certificate issued by a legitimate Certification Authority, a related issue to CVE-2009-2408.

This issue affects the versions of the openldap package, as shipped with Red Hat Enterprise Linux 3, 4, and 5. This issue affects the versions of the openldap package, as shipped with Fedora releases of 10 (openldap-2.4.12-1.fc10), 11 (openldap-2.4.15-6.fc11) and as scheduled to appear in Fedora of release 12 (openldap-2.4.18-5.fc12). Please fix.
This issue affects openldap versions as shipped in Red Hat Enterprise Linux 3, 4, and 5. Due to how OpenLDAP is typically deployed, the exposure of this flaw is limited. A malicious attacker would need to perform attacks on a local network to perform a Man-in-the-Middle attack (ARP spoofing, fake AP, control over an intermediate node, or DNS hijacking), as well as having a crafted certificate that OpenLDAP would see as valid from an authorized and trusted Certificate Authority. This was rated as having moderate security impact. Future openldap updates may address this flaw. We do not currently plan to release updates to address only this flaw.
openldap-2.4.15-7.fc11 has been pushed to the Fedora 11 stable repository. If problems still persist, please make note of it in this bug report.
