CVE-2009-2700

Date: September 2, 2009

src/network/ssl/qsslcertificate.cpp in Nokia Trolltech Qt 4.x does not properly handle a '\0' character in a domain name in the Subject Alternative Name 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.
