CVE-2012-4930

Public: 2012-09-13
Bugzilla: 857737: CVE-2012-4930 SPDY: SSL/TLS CRIME attack

Details

The MITRE CVE dictionary describes this issue as:

The SPDY protocol 3 and earlier, as used in Mozilla Firefox, Google Chrome, and other products, can perform TLS encryption of compressed data without properly obfuscating the length of the unencrypted data, which allows man-in-the-middle attackers to obtain plaintext 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, aka a "CRIME" attack.

Statement

Not vulnerable. This issue did not affect the versions of Firefox as shipped with Red Hat Enterprise Linux 5 and 6 as they did not include SPDY protocol support.
