Multiple integer overflows in the read_bitmap_file_data function in io-xbm.c in gdk-pixbuf before 2.26.1 allow remote attackers to cause a denial of service (application crash) via a negative (1) height or (2) width in an XBM file, which triggers a heap-based buffer overflow.

The remote Redhat Enterprise Linux 6 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - gdk-pixbuf: DoS (GLib error and application abort) due to an integer overflow in the XBM image file format     loader (CVE-2012-2370)

  - gtk2, gtk3: Integer overflow in image handling (CVE-2013-7447)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

The remote Solaris system is missing necessary patches to address security updates :

  - Multiple integer overflows in the read_bitmap_file_data     function in io-xbm.c in gdk-pixbuf before 2.26.1 allow     remote attackers to cause a denial of service     (application crash) via a negative (1) height or (2)     width in an XBM file, which triggers a heap-based buffer     overflow. (CVE-2012-2370)

Fix integer overflow in XBM file loader. Fix bnc#762735, CVE-2012-2370.

From Red Hat Security Advisory 2013:0135 :

Updated gtk2 packages that fix one security issue and several bugs are now available for Red Hat Enterprise Linux 5.

The Red Hat Security Response Team has rated this update as having low 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.

GIMP Toolkit (GTK+) is a multi-platform toolkit for creating graphical user interfaces.

An integer overflow flaw was found in the X BitMap (XBM) image file loader in GTK+. A remote attacker could provide a specially crafted XBM image file that, when opened in an application linked against GTK+ (such as Nautilus), would cause the application to crash.
(CVE-2012-2370)

This update also fixes the following bugs :

* Due to a bug in the Input Method GTK+ module, the usage of the Taiwanese Big5 (zh_TW.Big-5) locale led to the unexpected termination of certain applications, such as the GDM greeter. The bug has been fixed, and the Taiwanese locale no longer causes applications to terminate unexpectedly. (BZ#487630)

* When a file was initially selected after the GTK+ file chooser dialog was opened and the Location field was visible, pressing the Enter key did not open the file. With this update, the initially selected file is opened regardless of the visibility of the Location field. (BZ#518483)

* When a file was initially selected after the GTK+ file chooser dialog was opened and the Location field was visible, pressing the Enter key did not change into the directory. With this update, the dialog changes into the initially selected directory regardless of the visibility of the Location field. (BZ#523657)

* Previously, the GTK Print dialog did not reflect the user-defined printer preferences stored in the ~/.cups/lpoptions file, such as those set in the Default Printer preferences panel. Consequently, the first device in the printer list was always set as a default printer.
With this update, the underlying source code has been enhanced to parse the option file. As a result, the default values in the print dialog are set to those previously specified by the user. (BZ#603809)

* The GTK+ file chooser did not properly handle saving of nameless files. Consequently, attempting to save a file without specifying a file name caused GTK+ to become unresponsive. With this update, an explicit test for this condition has been added into the underlying source code. As a result, GTK+ no longer hangs in the described scenario. (BZ#702342)

* When using certain graphics tablets, the GTK+ library incorrectly translated the input coordinates. Consequently, an offset occurred between the position of the pen and the content drawn on the screen.
This issue was limited to the following configuration: a Wacom tablet with input coordinates bound to a single monitor in a dual head configuration, drawing with a pen with the pressure sensitivity option enabled. With this update, the coordinate translation method has been changed, and the offset is no longer present in the described configuration. (BZ#743658)

* Previously, performing drag and drop operations on tabs in applications using the GtkNotebook widget could lead to releasing the same resource twice. Eventually, this behavior caused the applications to terminate with a segmentation fault. This bug has been fixed, and the applications using GtkNotebook no longer terminate in the aforementioned scenario. (BZ#830901)

All users of GTK+ are advised to upgrade to these updated packages, which contain backported patches to correct these issues.

The following issue has been fixed :

  - Specially crafted GIF and XBM files could have crashed     gtk2 (CVE-2012-2370 / CVE-2011-2485)

This update of gdk-pixbuf fixes multiple buffer overflows that could have caused a crash or potentially have allowed heap corruptions.

This update fixes :

  - Bug #822471 - CVE-2012-2370 gdk-pixbuf, gdk-pixbuf2:
    Integer overflow in the XBM image file format loader     [fedora-all]

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.

The following issue has been fixed :

  - Specially crafted GIF and XBM files could have crashed     gtk2. (CVE-2012-2370 / CVE-2011-2485)

The remote host is affected by the vulnerability described in GLSA-201206-20 (gdk-pixbuf: Denial of Service)

    Two vulnerabilities have been found in gdk-pixbuf:
      The 'gdk_pixbuf__gif_image_load()' function in io-gif.c fails to         properly handle certain return values from subroutines (CVE-2011-2485).
      The 'read_bitmap_file_data()' function in io-xbm.c contains an         integer overflow error (CVE-2012-2370).
  Impact :

    A remote attacker could entice a user to open a specially crafted image       in an application linked against gdk-pixbuf, possibly resulting in Denial       of Service.
  Workaround :

    There is no known workaround at this time.
