The remote Oracle Linux 6 host has packages installed that are affected by a vulnerability as referenced in the ELSA-2013-0669 advisory.

    [1:4.6.2-26]
    - Resolves: CVE-2013-0254, QSharedMemory class created shared memory segments with insecure permissions

Tenable has extracted the preceding description block directly from the Oracle Linux security advisory.

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

libqt4 was updated to fix a information disclosure via QSharedMemory (CVE-2013-0254).

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)

Updated qt packages that fix one security issue are now available for Red Hat Enterprise Linux 6.

The Red Hat Security Response Team has rated this update as having moderate security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section.

Qt is a software toolkit that simplifies the task of writing and maintaining GUI (Graphical User Interface) applications for the X Window System.

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)

Red Hat would like to thank the Qt project for reporting this issue.
Upstream acknowledges Tim Brown and Mark Lowe of Portcullis Computer Security Ltd. as the original reporters.

Users of Qt should upgrade to these updated packages, which contain a backported patch to correct this issue. All running applications linked against Qt libraries must be restarted for this update to take effect.

This update fixes multiple security issues in the Qt library.

CVE-2013-0254

The QSharedMemory class uses weak permissions (world-readable and world-writable) for shared memory segments, which allows local users to read sensitive information or modify critical program data, as demonstrated by reading a pixmap being sent to an X server.

CVE-2015-0295 / CVE-2015-1858 / CVE-2015-1859 / CVE-2015-1860

Denial of service (via segmentation faults) through crafted images (BMP, GIF, ICO).

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