DESCRIPTION:
Two vulnerabilities have been reported in Microsoft Windows, which
can be exploited by malicious people to manipulate certain data or to
compromise a vulnerable system.

1) An unspecified error exists in SChannel when processing
certificate request messages on a client machine. This may be
exploited to execute arbitrary code e.g. when a user visits a
specially crafted web site.

2) An error in the TLS and SSL protocols while handling session
renegotiations can be exploited to manipulate certain data.
