Fedora 9: 2009-3710 Critical Ghostscript Buffer Overflow Advisory

Ghostscript is a set of software that provides a PostScript(TM)

interpreter, a set of C procedures (the Ghostscript library, which

implements the graphics capabilities in the PostScript language) and

an interpreter for Portable Document Format (PDF) files. Ghostscript

translates PostScript code into many common, bitmapped formats, like

those understood by your printer or screen. Ghostscript is normally

used to display PostScript files and to print PostScript files to

non-PostScript printers.

If you need to display PostScript files or print them to

non-PostScript printers, you should install ghostscript. If you

install ghostscript, you also need to install the ghostscript-fonts

package.

This update fixes several security flaws: CVE-2009-0792 (multiple integer

overflows and missing upper-bounds checks in icclib), CVE-2009-0196 (missing

boundary check in jbig2dec library), and CVE-2008-6679 (buffer overflow in

pdfwrite device).
