Synopsis |
| 17 |
======== |
| 18 |
|
| 19 |
Poppler does not handle fonts inside PDF files safely, allowing for |
| 20 |
execution of arbitrary code. |
| 21 |
|
| 22 |
Background |
| 23 |
========== |
| 24 |
|
| 25 |
Poppler is a cross-platform PDF rendering library originally based on |
| 26 |
Xpdf. |
| 27 |
|
| 28 |
Affected packages |
| 29 |
================= |
| 30 |
|
| 31 |
------------------------------------------------------------------- |
| 32 |
Package / Vulnerable / Unaffected |
| 33 |
------------------------------------------------------------------- |
| 34 |
1 app-text/poppler < 0.6.3 >= 0.6.3 |
| 35 |
|
| 36 |
Description |
| 37 |
=========== |
| 38 |
|
| 39 |
Kees Cook from the Ubuntu Security Team reported that the |
| 40 |
CairoFont::create() function in the file CairoFontEngine.cc does not |
| 41 |
verify the type of an embedded font object inside a PDF file before |
| 42 |
dereferencing a function pointer from it. |
| 43 |
|
| 44 |
Impact |
| 45 |
====== |
| 46 |
|
| 47 |
A remote attacker could entice a user to open a specially crafted PDF |
| 48 |
file with a Poppler-based PDF viewer such as Gentoo's Xpdf, Epdfview, |
| 49 |
or Evince, potentially resulting in the execution of arbitrary code |
| 50 |
with the privileges of the user running the application. |
| 51 |
|
| 52 |
Workaround |
| 53 |
========== |
| 54 |
|
| 55 |
There is no known workaround at this time. |
| 56 |
|
| 57 |
Resolution |
| 58 |
========== |
| 59 |
|
| 60 |
All Poppler users should upgrade to the latest version: |
| 61 |
|
| 62 |
# emerge --sync |
| 63 |
# emerge --ask --oneshot --verbose ">=app-text/poppler-0.6.3" |
| 64 |
|
