Debian Security Advisory DSA 508-1 - Jaguar discovered a vulnerability in one component of xpcd, a PhotoCD viewer. xpcd-svga, part of xpcd which uses svgalib to display graphics on the console, would copy user-supplied data of arbitrary length into a fixed-size buffer in the pcd_open function.

Jaguar discovered a vulnerability in one component of xpcd, a PhotoCD
viewer.  xpcd-svga, part of xpcd which uses svgalib to display
graphics on the console, would copy user-supplied data of arbitrary
length into a fixed-size buffer in the pcd_open function.

For the current stable distribution (woody) this problem has been
fixed in version 2.08-8woody2.

For the unstable distribution (sid), this problem will be fixed soon.

We recommend that you update your xpcd package.

Upgrade Instructions
- --------------------

wget url
        will fetch the file for you

        will install the referenced file.

If you are using the apt-get package manager, use the line for
sources.list as given below:

apt-get update
        will update the internal database
apt-get upgrade
        will install corrected packages

You may use an automated update by adding the resources from the
footer to the proper configuration.

xpcd/libpcd Image Error Overflow
Local Access Required Input Manipulation
Loss of Integrity
Exploit Unknown

- 漏洞描述

A local overflow exists in xpcd. The pcd_open function fails to validate user input resulting in a buffer overflow. With a specially crafted request, an attacker can cause arbitrary code execution resulting in a loss of integrity.

- 漏洞讨论

The xpcd-svga utility is susceptible to a locally exploitable buffer overflow condition. According to the report, xpcd-svga copies untrusted data into a buffer of predefined size without bounds checking. The procedure where this occurs is "pcd_open()", suggesting that the source of the data may be in the image file or photo disk.
