Description Huzaifa S. Sidhpurwala 2012-09-24 02:44:50 EDT
Security researchers Thai Duong and Juliano Rizzo reported that SPDY's request header compression leads to information leakage, which can allow the extraction of private data such as session cookies, even over an encrypted SSL connection.

Comment 1 Huzaifa S. Sidhpurwala 2012-09-24 02:46:04 EDT
Red Hat Enterprise Linux 5 and 6 currently contain Mozilla Firefox version 10.0.x ESR.  Those versions:

- do not request the use of zlib compression in the SSL/TLS protocol
- do not support SPDY protocol

(See bug 857051, comment 4 and bug 857737 for more details).

Statement:

This issue did not affect the version of Firefox and Thunderbird packages as shipped with Red Hat Enterprise Linux 5 and 6.
Comment 2 Huzaifa S. Sidhpurwala 2012-09-24 02:50:57 EDT
