"The SPDY protocol 3, and earlier, can perform TLS encryption of
compressed data without properly obfuscating the length of the
unencrypted data. This allows man-in-the-middle attackers to obtain
plain text HTTP headers by observing length differences during a
series of guesses in which a string in an HTTP request potentially
matches an unknown string in an HTTP header. The SPDY protocol 3, and
earlier, is used in Mozilla Firefox, Google Chrome, and other
products. (CVE-2012-4930)

Impact

Connections to virtual servers configured with the SPDY profile may be
at risk."
