QT maintainers, I checked the status of QT in Lenny and 4.6.2 from
Squeeze throughout the recent weeks:

The following vulnerabilties are fixed in 4.6.2 and Lenny:
CVE-2009-1691, CVE-2009-1699, CVE-2009-1711, CVE-2009-1712
CVE-2009-1713, CVE-2009-2816 (Lenny not affected), 
CVE-2009-2841 (Lenny not affected), CVE-2009-1688, CVE-2009-1689
CVE-2009-1695 (Lenny not affected), CVE-2009-1696 (Lenny not affected)
CVE-2009-1703 (Lenny not affected)

The following vulnerabilities are fixed in 4.6.2, but unfixed in Lenny:
CVE-2006-2783, CVE-2008-2307, CVE-2009-1692, CVE-2009-3384
CVE-2008-3632, CVE-2009-2797, CVE-2009-1681, CVE-2009-1684
CVE-2009-1685, CVE-2009-1686, CVE-2009-1694, CVE-2009-1697
CVE-2009-1700, CVE-2009-1701, CVE-2009-1702, CVE-2009-1710
CVE-2009-1715, CVE-2009-1718, CVE-2009-1714
Since they're all limited to webkit and QtWebkit and since Lenny
doesn't yet provide a browser based on QtWebKit, I don't think
we need to update it (this will be different from Squeeze onwards,
though. Or do you have a different opionion on that matter?

The following vulnerabilities don't affect Lenny nor Squeeze:
CVE-2008-0298: Doesn't affect QT (or was fixed years ago)
CVE-2008-1588: This is MacOS-specific.
CVE-2008-2320: This doesn't affect Webkit or QT.
CVE-2009-2953: Not treated as a security issue
CVE-2008-4724: Unclear, but of negligable impact
CVE-2008-4231: Apparently Safari-only

This leaves us with one vulnerability, which is apparently still
unfixed in 4.6.2:

CVE-2009-1693: Webkit commit: http://trac.webkit.org/changeset/35928

Could you please contact upstream whether this is an oversight or
was left out intentionally? 

Since CVE-2009-1693 is of low impact, I'm lowering severity to
"important", but please try to get it resolved for Squeeze.

Cheers,
