Stack-based buffer overflow in Google Chrome before 16.0.912.75 allows remote attackers to cause a denial of service or possibly have unspecified other impact via vectors related to glyph handling.

A stack-based buffer overflow in the glyph handling of libqt4's harfbuzz has been fixed. CVE-2011-3922 has been assigned to this issue.

fix stack based overflow in harbuzz parser

Chromium update to version 18.0.1022 fixes several security issues

From Red Hat Security Advisory 2012:0880 :

Updated qt packages that fix two security issues and three bugs are now available for Red Hat Enterprise Linux 6.

The Red Hat Security Response Team has rated this update as having moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links 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. 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-2011-3922)

A flaw was found in the way Qt handled X.509 certificates with IP address wildcards. An attacker able to obtain a certificate with a Common Name containing an IP wildcard could possibly use this flaw to impersonate an SSL server to client applications that are using Qt.
This update also introduces more strict handling for hostname wildcard certificates by disallowing the wildcard character to match more than one hostname component. (CVE-2010-5076)

This update also fixes the following bugs :

* The Phonon API allowed premature freeing of the media object.
Consequently, GStreamer could terminate unexpectedly as it failed to access the released media object. This update modifies the underlying Phonon API code and the problem no longer occurs. (BZ#694684)

* Previously, Qt could output the 'Unrecognized OpenGL version' error and fall back to OpenGL-version-1 compatibility mode. This happened because Qt failed to recognize the version of OpenGL installed on the system if the system was using a version of OpenGL released later than the Qt version in use. This update adds the code for recognition of OpenGL versions to Qt and if the OpenGL version is unknown, Qt assumes that the last-known version of OpenGL is available. (BZ#757793)

* Previously Qt included a compiled-in list of trusted CA (Certificate Authority) certificates, that could have been used if Qt failed to open a system's ca-bundle.crt file. With this update, Qt no longer includes compiled-in CA certificates and only uses the system bundle.
(BZ#734444)

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.

This build addresses a security issue :

  - CVE-2011-3922 qt: Stack-based buffer overflow in     embedded harfbuzz code

as well as includes an upstream patch to address :

  - 'closed windows stay in the taskbar sometimes, taskbar     doesn't react on clicks', http://bugs.kde.org/275469

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.

Versions of Google Chrome earlier than 16.0.912.75 are potentially affected by multiple vulnerabilities :

  - A heap-based buffer overflow exists in libxml. (CVE-2011-3919)

  - A use-after-free error exists related to animation frames. (CVE-2011-3921)

  - A stack-based-buffer overflow exists related to glyph processing. (CVE-2011-3922)

The version of Google Chrome installed on the remote host is earlier than 16.0.912.75 and is affected the following vulnerabilities:

  - A heap-based buffer overflow exists related to 'libxml'.
    (CVE-2011-3919)

  - A use-after-free error exists related to animation     frames. (CVE-2011-3921)

  - A stack-based buffer overflow exists related to glyph     processing. (CVE-2011-3922)

The remote host is affected by the vulnerability described in GLSA-201201-03 (Chromium, V8: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in Chromium and V8. Please       review the CVE identifiers and release notes referenced below for       details.
  Impact :

    A context-dependent attacker could entice a user to open a specially       crafted website or JavaScript program using Chromium or V8, possibly       resulting in the execution of arbitrary code with the privileges of the       process, or a Denial of Service condition.
    The attacker could also perform URL bar spoofing.
  Workaround :

    There is no known workaround at this time.
