Synopsis |
| 15 |
======== |
| 16 |
|
| 17 |
Multiple integer overflows were discovered in Xpdf, potentially |
| 18 |
resulting in execution of arbitrary code upon viewing a malicious PDF |
| 19 |
file. CUPS includes Xpdf code and therefore is vulnerable to the same |
| 20 |
issues. |
| 21 |
|
| 22 |
Background |
| 23 |
========== |
| 24 |
|
| 25 |
Xpdf is an open source viewer for Portable Document Format (PDF) files. |
| 26 |
The Common UNIX Printing System (CUPS) is a cross-platform print |
| 27 |
spooler that includes some Xpdf code. |
| 28 |

Description |
| 42 |
=========== |
| 43 |
|
| 44 |
Chris Evans discovered multiple integer overflow issues in Xpdf. |
| 45 |
|
| 46 |
Impact |
| 47 |
====== |
| 48 |
|
| 49 |
An attacker could entice an user to open a specially-crafted PDF file, |
| 50 |
potentially resulting in execution of arbitrary code with the rights of |
| 51 |
the user running Xpdf. By enticing an user to directly print the PDF |
| 52 |
file to a CUPS printer, an attacker could also crash the CUPS spooler |
| 53 |
or execute arbitrary code with the rights of the CUPS spooler, which is |
| 54 |
usually the "lp" user. |
| 55 |
|
| 56 |
Workaround |
| 57 |
========== |
| 58 |
|
| 59 |
There is no known workaround at this time. |
| 60 |
|
| 61 |
Resolution |
| 62 |
========== |
| 63 |
|
| 64 |
All Xpdf users should upgrade to the latest version: |
| 65 |
|
| 66 |
# emerge sync |
| 67 |
|
| 68 |
# emerge -pv ">=app-text/xpdf-3.00-r3" |
| 69 |
# emerge ">=app-text/xpdf-3.00-r3" |
| 70 |
|
| 71 |
All CUPS users should also upgrade to the latest version: |
| 72 |
|
| 73 |
# emerge sync |
| 74 |
|
| 75 |
# emerge -pv ">=net-print/cups-1.1.20-r4" |
| 76 |
# emerge ">=net-print/cups-1.1.20-r4" |
| 77 |
