This update fixes CVE-2013-4549 (XML Entity Expansion Denial of Service) in Qt 3. See the Qt Project Security Advisory for details:
http://lists.qt-project.org/pipermail/announce/2013-December/000036.ht ml
In addition, this update fixes :
QTBUG-35459, a too low character limit for XML entities enforced by the fix for CVE-2013-4549 that was breaking real-world XML files (in particular, the KatePart Lilypond syntax highlighting description),
QTBUG-35460, a misspelling in the error message produced by the CVE-2013-4549 fix when the character limit for XML entities was exceeded,
some minor format string abuse that was probably not exploitable (most instances definitely weren’t).
Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
