Gentoo Linux Security Advisory

Title: QtCore, QtGui: Multiple vulnerabilities (GLSA 201311-14)
Severity: normal
Exploitable: remote
Date: November 22, 2013
Bug(s): #361401, #382171, #384103, #455884
ID: 201311-14

Synopsis

Multiple vulnerabilities have been discovered in QtCore and QtGui,
possibly resulting in execution of arbitrary code, Denial of Service, or
man-in-the-middle attacks.


Background

The Qt toolkit is a comprehensive C++ application development framework.

Affected Packages

Package: dev-qt/qtcore
Vulnerable: < 4.8.4-r2
Unaffected: >= 4.8.4-r2
Architectures: All supported architectures

Package: dev-qt/qtgui
Vulnerable: < 4.8.4-r1
Unaffected: >= 4.8.4-r1
Architectures: All supported architectures


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:
Code:
# emerge --sync
      # emerge --ask --oneshot --verbose ">=dev-qt/qtcore-4.8.4-r2"
   
All QtGui users should upgrade to the latest version:
Code:
# 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.
