CVE-2014-1492: Input Validation

First published: Mon Mar 24 2014(Updated: )

In a wildcard certificate, the wildcard character should not be embedded within the U-label of an internationalized domain name. This was not properly implemented in NSS, as a result it did not handle IDNA domain prefixes according to RFC 6125, section 6.4.3 "Checking of Wildcard Certificates". <a href="http://tools.ietf.org/html/rfc6125#section-6.4.3">http://tools.ietf.org/html/rfc6125#section-6.4.3</a> Upstream patch: <a href="https://hg.mozilla.org/projects/nss/rev/15ea62260c21">https://hg.mozilla.org/projects/nss/rev/15ea62260c21</a> <a href="https://hg.mozilla.org/projects/nss/rev/2ffa40a3ff55">https://hg.mozilla.org/projects/nss/rev/2ffa40a3ff55</a> <a href="https://hg.mozilla.org/projects/nss/rev/709d4e597979">https://hg.mozilla.org/projects/nss/rev/709d4e597979</a> Upstream bug (not public): <a href="https://bugzilla.mozilla.org/show_bug.cgi?id=903885">https://bugzilla.mozilla.org/show_bug.cgi?id=903885</a> This issue was fixed upstream in NSS 3.16: <a href="https://developer.mozilla.org/en-US/docs/NSS/NSS_3.16_release_notes">https://developer.mozilla.org/en-US/docs/NSS/NSS_3.16_release_notes</a>
