Stack-based buffer overflow in QXmlSimpleReader in Qt 4.8.5 allows remote attackers to cause a denial of service (application crash) via a xml file with multiple nested open tags.

The remote NewStart CGSL host, running version MAIN 6.06, has qt5-qtbase packages installed that are affected by multiple vulnerabilities:

  - Stack-based buffer overflow in QXmlSimpleReader in Qt 4.8.5 allows remote attackers to cause a denial of     service (application crash) via a xml file with multiple nested open tags. (CVE-2016-10040)

  - Multiple buffer overflows in gui/image/qgifhandler.cpp in the QtBase module in Qt before 4.8.7 and 5.x     before 5.4.2 allow remote attackers to cause a denial of service (segmentation fault) and possibly execute     arbitrary code via a crafted GIF image. (CVE-2015-1860)

  - 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. (CVE-2013-4549)

  - The BMP decoder in QtGui in QT before 5.5 does not properly calculate the masks used to extract the color     components, which allows remote attackers to cause a denial of service (divide-by-zero and crash) via a     crafted BMP file. (CVE-2015-0295)

  - Multiple buffer overflows in gui/image/qbmphandler.cpp in the QtBase module in Qt before 4.8.7 and 5.x     before 5.4.2 allow remote attackers to cause a denial of service (segmentation fault and crash) and     possibly execute arbitrary code via a crafted BMP image. (CVE-2015-1858)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - Stack-based buffer overflow in QXmlSimpleReader in Qt 4.8.5 allows remote attackers to cause a denial of     service (application crash) via a xml file with multiple nested open tags. (CVE-2016-10040)

Note that Nessus relies on the presence of the package as reported by the vendor.

This update fixes CVE-2016-10040, a stack overflow in QXmlSimpleReader due to a too lenient entityCharacterLimit in our version of the patch for CVE-2013-4549. (The limit was increased from the upstream 1024 to 65536 to address QTBUG-35459, an issue where the security fix was breaking existing real-world XML files. Unfortunately, that is too much to actually fit on the CPU stack. This fix decreases the limit to 4096.)
