http://security.gentoo.org/

Severity:	normal
Title:	QtGui: Multiple vulnerabilities
Date:	03/12/2016
Bugs:	#546174
ID:	201603-10

Synopsis

Multiple vulnerabilities have been found in QtGui allowing remote attackers to execute arbitrary code or cause Denial of Service.

Background

QtGui is the GUI module and platform plugins for the Qt framework

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
dev-qt/qtgui	< 5.4.1-r1	>= 5.4.1-r1	All supported architectures

Description

Multiple buffer overflow vulnerabilities have been discovered in QtGui. It is possible for remote attackers to construct specially crafted BMP, ICO, or GIF images that lead to buffer overflows. After successfully overflowing the buffer the remote attacker can then cause a Denial of Service or execute arbitrary code.

Impact

A remote attacker could possibly execute arbitrary code or cause Denial of Service.

Workaround

There is no known work around at this time.

Resolution

All QtGui 4.8 users should upgrade to the latest version:

      # emerge --sync
      # emerge --ask --oneshot --verbose ">=dev-qt/qtgui-4.8.6-r4"

All QtGui 5.4 users should upgrade to the latest version:


      # emerge --sync
      # emerge --ask --oneshot --verbose ">=dev-qt/qtgui-5.4.1-r1"
