Several security issues were fixed in Qt.

Summary

Several security issues were fixed in Qt.

Software Description:

- qt4-x11: Qt 4 libraries

Details:

Richard J. Moore and Peter Hartmann discovered that Qt allowed redirecting

requests from http to file schemes. If an attacker were able to perform a

man-in-the-middle attack, this flaw could be exploited to view sensitive

information. This issue only affected Ubuntu 11.10, Ubuntu 12.04 LTS,

and Ubuntu 12.10. (CVE-2012-5624)

Stephen Cheng discovered that Qt may report incorrect errors when ssl

certificate verification fails. (CVE-2012-6093)

Tim Brown and Mark Lowe discovered that Qt incorrectly used weak

permissions on shared memory segments. A local attacker could use this

issue to view sensitive information, or modify program data belonging to

other users. (CVE-2013-0254)
