RHEL 6 : qt (RHSA-2011:1328)

critical Nessus Plugin ID 56255

Language:

Synopsis

The remote Red Hat host is missing one or more security updates for qt.

Description

The remote Redhat Enterprise Linux 6 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2011:1328 advisory.

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

A buffer overflow flaw was found in the harfbuzz module in Qt. If a user loaded a specially-crafted font file with an application linked against Qt, it could cause the application to crash or, possibly, execute arbitrary code with the privileges of the user running the application.
(CVE-2011-3193)

A buffer overflow flaw was found in the way Qt handled certain gray-scale image files. If a user loaded a specially-crafted gray-scale image file with an application linked against Qt, it could cause the application to crash or, possibly, execute arbitrary code with the privileges of the user running the application. (CVE-2011-3194)

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

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

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

Solution

Update the RHEL qt package based on the guidance in RHSA-2011:1328.
