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      /  Vulnerable  /                          Unaffected

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:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=x11-libs/qt-3.3.8-r4"
