Medium Nessus Plugin ID 71518


The remote Ubuntu host is missing one or more security-related patches.


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.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.


Update the affected libqt4-xml and / or libqt5xml5 packages.
