Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
Adobe Acrobat Reader is vulnerable to remote code execution, Denial of |
| 19 |
Service, and cross-site scripting attacks. |
| 20 |
|
| 21 |
Background |
| 22 |
========== |
| 23 |
|
| 24 |
Adobe Acrobat Reader is a PDF reader released by Adobe. |
| 25 |
|
| 26 |
Affected packages |
| 27 |
================= |

|
| 29 |
------------------------------------------------------------------- |
| 30 |
Package / Vulnerable / Unaffected |
| 31 |
------------------------------------------------------------------- |
| 32 |
1 app-text/acroread < 7.0.9 >= 7.0.9 |

|
| 34 |
Description |
| 35 |
=========== |
| 36 |
|
| 37 |
Adobe Acrobat Reader in stand-alone mode is vulnerable to remote code |
| 38 |
execution via heap corruption when loading a specially crafted PDF |
| 39 |
file. |
| 40 |
|
| 41 |
The browser plugin released with Adobe Acrobat Reader (nppdf.so) does |
| 42 |
not properly handle URLs, and crashes if given a URL that is too long. |
| 43 |
The plugin does not correctly handle JavaScript, and executes |
| 44 |
JavaScript that is given as a GET variable to the URL of a PDF file. |
| 45 |
Lastly, the plugin does not properly handle the FDF, xml, xfdf AJAX |
| 46 |
request parameters following the # character in a URL, allowing for |
| 47 |
multiple cross-site scripting vulnerabilities. |
| 48 |
|
| 49 |
Impact |
| 50 |
====== |
| 51 |
|
| 52 |
An attacker could entice a user to open a specially crafted PDF file |
| 53 |
and execute arbitrary code with the rights of the user running Adobe |
| 54 |
Acrobat Reader. An attacker could also entice a user to browse to a |
| 55 |
specially crafted URL and either crash the Adobe Acrobat Reader browser |
| 56 |
plugin, execute arbitrary JavaScript in the context of the user's |
| 57 |
browser, or inject arbitrary HTML or JavaScript into the document being |
| 58 |
viewed by the user. Note that users who have emerged Adobe Acrobat |
| 59 |
Reader with the "nsplugin" USE flag disabled are not vulnerable to |
| 60 |
issues with the Adobe Acrobat Reader browser plugin. |
| 61 |
|
| 62 |
Workaround |
| 63 |
========== |
| 64 |
|
| 65 |
There is no known workaround at this time. |
| 66 |
|
| 67 |
Resolution |
| 68 |
========== |
| 69 |
|
| 70 |
All Adobe Acrobat Reader users should upgrade to the latest version: |
| 71 |
|
| 72 |
# emerge --sync |
| 73 |
# emerge --ask --oneshot --verbose ">=app-text/acroread-7.0.9" |
| 74 |
|
