Description Ionen Wolkens gentoo-dev 2024-05-21 06:39:50 UTC
Release notes for Qt 6.7.1[1] mention having fixed CVE-2024-36048, but Qt has not done a blog post about it (yet) that I can see so have little details beside the CVE's description:

    QAbstractOAuth in Qt Network Authorization in Qt before 5.15.17, 6.x before 6.2.13, 6.3.x through 6.5.x before 6.5.6, and 6.6.x through 6.7.x before 6.7.1 uses only the time to seed the PRNG, which may result in guessable values.

And what seems to be the fix[2] for 6.7.1.

6.7.1 is already in-tree, pending stable in ~2 weeks or so if nothing comes up.

5.15.x still needs fixing (figure it may wait until Qt does a blog post w/ patches unless want to try to use 6.7.1's fix).
