NVD Description

Note: Versions mentioned in the description apply only to the upstream qt4-x11 package and not the qt4-x11 package as distributed by Debian. See How to fix? for Debian:10 relevant fixed versions and status.

The TLS protocol 1.2 and earlier, as used in Mozilla Firefox, Google Chrome, Qt, and other products, can encrypt 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.
