[GLSA-200409-28] GTK+ 2, gdk-pixbuf: Multiple image decoding vulnerabilities

Vulnerability Assessment Summary
GTK+ 2, gdk-pixbuf: Multiple image decoding vulnerabilities

Detailed Explanation for this Vulnerability Assessment
The remote host is affected by the vulnerability described in GLSA-200409-28
(GTK+ 2, gdk-pixbuf: Multiple image decoding vulnerabilities)


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

Impact

With a specially crafted BMP image a possible hacker 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 a possible hacker
could trigger the overflows, which potentially permits the execution of
arbitrary code.

Workaround

There is no known workaround at this time.
