<title>GTK+ 2, gdk-pixbuf: Multiple image decoding vulnerabilities</title>
|
|
<synopsis>
|
|
The GdkPixbuf library, which is also included in GTK+ 2, contains several
|
|
vulnerabilities that could lead to a Denial of Service or the execution of
|
|
arbitrary code.

GTK+ (GIMP Toolkit +) is a toolkit for creating graphical user interfaces.
|
|
The GdkPixbuf library provides facilities for image handling. It is
|
|
available as a standalone library as well as shipped with GTK+ 2.

A vulnerability has been discovered in the BMP image preprocessor
|
|
(CAN-2004-0753). Furthermore, Chris Evans found a possible integer overflow
|
|
in the pixbuf_create_from_xpm() function, resulting in a heap overflow
|
|
(CAN-2004-0782). He also found a potential stack-based buffer overflow in
|
|
the xpm_extract_color() function (CAN-2004-0783). A possible integer
|
|
overflow has also been found in the ICO decoder.

<impact type="normal">
|
|
<p>
|
|
With a specially crafted BMP image an attacker could cause an affected
|
|
application to enter an infinite loop when that image is being processed.
|
|
Also, by making use of specially crafted XPM or ICO images an attacker
|
|
could trigger the overflows, which potentially allows the execution of
|
|
arbitrary code.

All GTK+ 2 users should upgrade to the latest version:
|

# emerge ">=x11-libs/gtk+-2.4.9-r1"</code>
