<title>QtGui: User-assisted execution of arbitrary code</title>

code or Denial of Service.

<vulnerable range="lt">4.7.4-r1</vulnerable>
<p>QtGui is a module for the Qt toolkit.</p>
<p>An error in qtiffhandler.cpp could cause a buffer overflow.</p>
<impact type="normal">
<p>A remote attacker could entice a user to open a specially crafted TIFF
image with an application linked against QtGui, possibly resulting in
execution of arbitrary code with the privileges of the process or a
Denial of Service condition.
<p>There is no known workaround at this time.</p>
<p>All QtGui users should upgrade to the latest version:</p>
# emerge --sync
# emerge --ask --oneshot --verbose "&gt;=x11-libs/qt-gui-4.7.4-r1"
<p>Packages which depend on this library may need to be recompiled. Tools
such as revdep-rebuild may assist in identifying some of these packages.
