Details

Juliano Rizzo and Thai Duong discovered a flaw in the Transport Layer
Security (TLS) protocol when it is used with data compression. If an
attacker were able to perform a machine-in-the-middle attack, this flaw
could be exploited to view sensitive information. This update disables
TLS data compression in Qt by default.
