CVE-2012-4930 (retired)

Priority
Description
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.
Notes
jdstrandFirefox 15 disables compression
For SPDY to be used with OpenSSL in any way, NPN must be available
in openssl. This was not introduced until 1.0.1. No patch for upstream
OpenSSL. This may be considered a flaw in the applications using OpenSSL and
not OpenSSL itself.
