Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
Multiple vulnerabilities have been discovered in Xpdf, GPdf, CUPS and |
| 19 |
Poppler potentially resulting in the execution of arbitrary code. |
| 20 |
|
| 21 |
Background |
| 22 |
========== |
| 23 |
|
| 24 |
Xpdf and GPdf are PDF file viewers that run under the X Window System. |
| 25 |
Poppler is a PDF rendering library based on Xpdf code. The Common UNIX |
| 26 |
Printing System (CUPS) is a cross-platform print spooler. It makes use |
| 27 |
of Xpdf code to handle PDF files. |

Description |
| 44 |
=========== |
| 45 |
|
| 46 |
infamous41md discovered that several Xpdf functions lack sufficient |
| 47 |
boundary checking, resulting in multiple exploitable buffer overflows. |
| 48 |
|
| 49 |
Impact |
| 50 |
====== |
| 51 |
|
| 52 |
An attacker could entice a user to open a specially-crafted PDF file |
| 53 |
which would trigger an overflow, potentially resulting in execution of |
| 54 |
arbitrary code with the rights of the user running Xpdf, CUPS, GPdf or |
| 55 |
Poppler. |
| 56 |
|
| 57 |
Workaround |
| 58 |
========== |
| 59 |
|
| 60 |
There is no known workaround at this time. |
| 61 |
|
| 62 |
