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 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.)

Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
