DESCRIPTION:
Some vulnerabilities have been reported in Xerox CopyCentre and Xerox
WorkCentre Pro, where one has an unknown impact, and others can be
exploited by malicious people to cause a DoS (Denial of Service).

1) An unspecified boundary error in the PostScript file interpreter
can be exploited to cause a buffer overflow.

Successful exploitation causes a denial of service on a vulnerable
device.

2) Two unspecified errors in the handling of PostScript files can be
exploited to cause a denial of service on a vulnerable device via a
specially crafted PostScript file.

3) An unspecified error in the built-in web server can be exploited
to cause a memory corruption.

Successful exploitation causes a denial of service on a vulnerable
device.

4) An unspecified error in the ESS / Network Controller causes an
image overwrite to fail in certain situations after a power loss.

The vulnerabilities affect the following products:
* Xerox CopyCentre C65, C75, and C90.
* Xerox WorkCentre Pro 65, 75, and 90.
