XEmacs JPEG buffer overflow
|xemacs-jpeg-bo (51334)||High Risk|
XEmacs is vulnerable to a heap-based buffer overflow, caused by an integer overflow in the jpeg_instantiate() function within glyphs-eimage.c. By persuading a victim to open a specially-crafted JPEG file, a remote attacker could overflow a buffer and execute arbitrary code on the system or cause the application to crash.
Apply the appropriate patch for your system. See References.

- 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.
