CVE-2009-2688

Multiple integer overflows in glyphs-eimage.c in XEmacs 21.4.22, when
running on Windows, allow remote attackers to cause a denial of service
(crash) or execute arbitrary code via (1) the tiff_instantiate function
processing a crafted TIFF file, (2) the png_instantiate function processing
a crafted PNG file, and (3) the jpeg_instantiate function processing a
crafted JPEG file, all which trigger a heap-based buffer overflow. NOTE:
the provenance of this information is unknown; the details are obtained
solely from third party information.
