CVE-2013-4549

It was discovered that QXmlSimpleReader in Qt incorrectly handled XML entity expansion. An attacker could use this flaw to cause Qt applications to consume large amounts of resources, resulting in a denial of service (CVE-2013-4549).

It was discovered that QXmlSimpleReader in Qt incorrectly handled XML entity expansion. An attacker could use this flaw to cause Qt applications to consume large amounts of resources, resulting in a denial of service (CVE-2013-4549)

Updated qt3 packages fix security vulnerabilities:

QXmlSimpleReader in Qt versions prior to 5.2 supports expansion of internal entities in XML documents without placing restrictions to ensure the document does not cause excessive memory usage. If an application using this API processes untrusted data then the application may use unexpected amounts of memory if a malicious document is processed (CVE-2013-4549).

A NULL pointer dereference flaw was found in QGIFFormat::fillRect in QtGui. If an application using the qt-x11 libraries opened a malicious GIF file with invalid width and height values, it could cause the application to crash (CVE-2014-0190)..

These are all security issues fixed in the libqt4-32bit-4.8.7-5.4 package on the GA media of openSUSE Tumbleweed.

These are all security issues fixed in the qt3-3.3.8c-140.6 package on the GA media of openSUSE Tumbleweed.

QXmlSimpleReader in Qt before 5.2 allows context-dependent attackers to cause a denial of service (memory consumption) via an XML Entity Expansion (XEE) attack.
