K14059 : CRIME vulnerability via the SPDY protocol CVE-2012-4930

Security Advisory Description

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.
