Background ========== The Qt toolkit is a comprehensive C++ application development framework. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 dev-qt/qtcore < 4.8.4-r2 >= 4.8.4-r2 2 dev-qt/qtgui < 4.8.4-r1 >= 4.8.4-r1 ------------------------------------------------------------------- 2 affected packages Description =========== Multiple vulnerabilities have been discovered in QtCore and QtGui. Please review the CVE identifiers referenced below for details. Impact ====== A remote attacker could entice a user to open a specially crafted file with an application linked against QtCore or QtGui, possibly resulting in execution of arbitrary code with the privileges of the process or a Denial of Service condition. Furthermore, a remote attacker might employ a specially crafted certificate to conduct man-in-the-middle attacks on SSL connections. Workaround ========== There is no known workaround at this time. Resolution ========== All QtCore users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=dev-qt/qtcore-4.8.4-r2" All QtGui users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=dev-qt/qtgui-4.8.4-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.
