Gentoo Linux Security Advisory

Title: Qt: Buffer overflow (GLSA 200710-28)
Severity: normal
Exploitable: remote
Date: October 25, 2007
Bug(s): #192472
ID: 200710-28

Synopsis


An off-by-one vulnerability has been discovered in Qt, possibly resulting
in the execution of arbitrary code.


Background


Qt is a cross-platform GUI framework, which is used e.g. by KDE.


Affected Packages

Package: x11-libs/qt
Vulnerable: < 3.3.8-r4
Unaffected: >= 3.3.8-r4
Architectures: All supported architectures


Description


Dirk Mueller from the KDE development team discovered a boundary error
in file qutfcodec.cpp when processing Unicode strings.


Impact


A remote attacker could send a specially crafted Unicode string to a
vulnerable Qt application, possibly resulting in the remote execution
of arbitrary code with the privileges of the user running the
application. Note that the boundary error is present but reported to be
not exploitable in 4.x series.


Workaround


There is no known workaround at this time.


Resolution


All Qt 3.x users should upgrade to the latest version:
Code:
# emerge --sync
    # emerge --ask --oneshot --verbose ">=x11-libs/qt-3.3.8-r4"


References

CVE-2007-4137
