Description Rex Dieter 2008-01-02 13:06:58 UTC

+++ This bug was initially created as a clone of Bug #411751 +++

Thiago José Macieira of Trolltech informed us of following problem affecting QT4
library:

Qt 4 has a potential vulnerability in QSslSocket, which might cause a
certificate verification in SSL connections not to be performed. As a 
consequence, code using QSslSocket might be mislead into thinking the 
certificate was verified correctly when it actually failed in one or more 
criteria.

Versions affected: 4.3.0, 4.3.1 and 4.3.2

This issue did not affect versions of qt and qt4 packages as shipped with Red
Hat Enterprise Linux 2.1, 3, 4, or 5.

Packages shipped are in version < 4.3 and do not contain vulnerable code.
