Detail

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 13.10 - Ubuntu 13.04 - Ubuntu 12.10 - Ubuntu 12.04 LTS

Summary:

Qt could be made to consume resources and hang if it processed XML data.

Software Description: - qt4-x11: Qt 4 libraries - qtbase-opensource-src: Qt 5 libraries

Details:

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.

Update instructions:

The problem can be corrected by updating your system to the following package versions:

Ubuntu 13.10:
libqt4-xml 4:4.8.4+dfsg-0ubuntu18.1
libqt5xml5 5.0.2+dfsg1-7ubuntu11.1

Ubuntu 13.04:
libqt4-xml 4:4.8.4+dfsg-0ubuntu9.5
libqt5xml5 5.0.1+dfsg-0ubuntu4.1

Ubuntu 12.10:
libqt4-xml 4:4.8.3+dfsg-0ubuntu3.2

Ubuntu 12.04 LTS:
libqt4-xml 4:4.8.1-0ubuntu4.5

After a standard system update you need to restart your session to make all the necessary changes.
