The remote host is affected by the vulnerability described in GLSA-201311-14 (QtCore, QtGui: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in QtCore and QtGui.
      Please review the CVE identifiers referenced below for details.
  Impact :

    A remote attacker could entice a user to open a specially crafted file       with an application linked against QtCore or QtGui, possibly resulting in       execution of arbitrary code with the privileges of the process or a       Denial of Service condition. Furthermore, a remote attacker might employ       a specially crafted certificate to conduct man-in-the-middle attacks on       SSL connections.
  Workaround :

    There is no known workaround at this time.

It was discovered that the QSharedMemory class implementation of the Qt toolkit created shared memory segments with insecure permissions. A local attacker could use this flaw to read or alter the contents of a particular shared memory segment, possibly leading to their ability to obtain sensitive information or influence the behavior of a process that is using the shared memory segment. (CVE-2013-0254)

All running applications linked against Qt libraries must be restarted for this update to take effect.

The remote Redhat Enterprise Linux 6 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2013:0669 advisory.

  - qt: QSharedMemory class created shared memory segments with insecure permissions (CVE-2013-0254)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

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).

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.

it fixes security flaw was found in the way QSharedMemory class, CVE-2013-0254

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.

libqt4 has been updated to fix several security issues.

  - An information disclosure via QSharedMemory was fixed     which allowed local attackers to read information (e.g.
    bitmap content) from the attacked user. (CVE-2013-0254)

  - openssl-incompatibility-fix.diff: Fix wrong error     reporting when using a binary incompatible version of     openSSL. (bnc#797006, CVE-2012-6093)

  - Various compromised SSL root certificates were     blacklisted. Also a non-security bugfix has been applied :

  - Add fix for qdbusviewer not matching args (bnc#784197)
