Microsoft is aware of improperly issued SSL certificates that could be
used in attempts to spoof content, perform phishing attacks, or
perform man-in-the-middle attacks. The SSL certificates were
improperly issued by the National Informatics Centre (NIC), which
operates subordinate CAs under root CAs operated by the Government of
India Controller of Certifying Authorities (CCA), which are CAs
present in the Trusted Root Certification Authorities Store. This
issue affects all supported releases of Microsoft Windows. Microsoft
is not currently aware of attacks related to this issue.

The subordinate CA has been misused to issue SSL certificates for
multiple sites, including Google web properties. These SSL
certificates could be used to spoof content, perform phishing attacks,
or perform man-in-the-middle attacks against web properties. The
subordinate CAs may also have been used to issue certificates for
other, currently unknown sites, which could be subject to similar
attacks.
