USN-1628-1: Qt vulnerability

08 November 2012

Qt applications could be made to expose sensitive information over the network.

Releases

Packages

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 man-in-the-middle attack, this flaw
could be exploited to view sensitive information. This update disables
TLS data compression in Qt by default.

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 12.04
Ubuntu 11.10
Ubuntu 10.04

After a standard system update you need to restart any KDE sessions or
applications linked against Qt to make all the necessary changes.
