Synopsis ========
A buffer overflow in QtGui could result in execution of arbitrary code or Denial of Service.
Background ==========
QtGui is a module for the Qt toolkit.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 x11-libs/qt-gui < 4.7.4-r1 >= 4.7.4-r1
Description ===========
An error in qtiffhandler.cpp could cause a buffer overflow.
Impact ======
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.
Workaround ==========
There is no known workaround at this time.
Resolution ==========
All QtGui users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=x11-libs/qt-gui-4.7.4-r1"
Packages which depend on this library may need to be recompiled. Tools such as revdep-rebuild may assist in identifying some of these packages.
