Pango is a library used for the layout and rendering of internationalized text.

A buffer overflow flaw was found in HarfBuzz, an OpenType text shaping engine used in Pango. If a user loaded a specially crafted font file with an application that uses Pango, it could cause the application to crash or, possibly, execute arbitrary code with the privileges of the user running the application. (CVE-2011-3193)

Users of pango are advised to upgrade to these updated packages, which contain a backported patch to resolve this issue. After installing this update, you must restart your system or restart the X server for the update to take effect.

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)

    Qt 4 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 flaw in the way Qt 4 expanded certain UTF-8 characters could be used to     prevent a Qt 4 based application from properly sanitizing user input.
    Depending on the application, this could allow an attacker to perform     directory traversal, or for web applications, a cross-site scripting (XSS)     attack. (CVE-2007-0242)

    A buffer overflow flaw was found in the harfbuzz module in Qt 4. If a user     loaded a specially-crafted font file with an application linked against Qt     4, it could cause the application to crash or, possibly, execute arbitrary     code with the privileges of the user running the application.

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.

Specially crafted font files could cause a single byte heap based buffer overflow (CVE-2011-3193).

Specially crafted grey scale images could cause a heap based buffer overflow (CVE-2011-3194).

CVE-2011-3194

Fix tiff reader to handle TIFFTAG_SAMPLESPERPIXEL for grayscale images. The reader uses QImage::Format_Indexed8, but since the samples per pixel value this should be (non-existent) QImage::Format_Indexed16, causing memory corruption. The fix falls back to the 'normal' way of reading tiff images.
