Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
Adobe Reader is vulnerable to execution of arbitrary code. |
| 19 |
|
| 20 |
Background |
| 21 |
========== |
| 22 |
|
| 23 |
Adobe Reader (formerly Adobe Acrobat Reader) is a closed-source PDF |
| 24 |
reader. |
| 25 |
|
| 26 |
Affected packages |
| 27 |
================= |
| 28 |
|
| 29 |
------------------------------------------------------------------- |
| 30 |
Package / Vulnerable / Unaffected |
| 31 |
------------------------------------------------------------------- |
| 32 |
1 app-text/acroread < 8.1.3 >= 8.1.3 |
| 33 |
|
| 34 |
Description |
| 35 |
=========== |
| 36 |
|
| 37 |
* An unspecified vulnerability can be triggered by a malformed PDF |
| 38 |
document, as demonstrated by 2008-HI2.pdf (CVE-2008-2549). |
| 39 |
|
| 40 |
* Peter Vreugdenhil, Dyon Balding, Will Dormann, Damian Frizza, and |
| 41 |
Greg MacManus reported a stack-based buffer overflow in the |
| 42 |
util.printf JavaScript function that incorrectly handles the format |
| 43 |
string argument (CVE-2008-2992). |
| 44 |
|
| 45 |
* Greg MacManus of iDefense Labs reported an array index error that |
| 46 |
can be leveraged for an out-of-bounds write, related to parsing of |
| 47 |
Type 1 fonts (CVE-2008-4812). |
| 48 |
|
| 49 |
* Javier Vicente Vallejo and Peter Vregdenhil, via Zero Day |
| 50 |
Initiative, reported multiple unspecified memory corruption |
| 51 |
vulnerabilities (CVE-2008-4813). |
| 52 |
|
| 53 |
* Thomas Garnier of SkyRecon Systems reported an unspecified |
| 54 |
vulnerability in a JavaScript method, related to an "input validation |
| 55 |
issue" (CVE-2008-4814). |
| 56 |
|
| 57 |
* Josh Bressers of Red Hat reported an untrusted search path |
| 58 |
vulnerability (CVE-2008-4815). |
| 59 |
|
| 60 |
* Peter Vreugdenhil reported through iDefense that the Download |
| 61 |
Manager can trigger a heap corruption via calls to the AcroJS |
| 62 |
function (CVE-2008-4817). |
| 63 |
|
| 64 |
Impact |
| 65 |
====== |
| 66 |
|
| 67 |
A remote attacker could entice a user to open a specially crafted PDF |
| 68 |
document, and local attackers could entice a user to run acroread from |
| 69 |
an untrusted working directory. Both might result in the execution of |
| 70 |
arbitrary code with the privileges of the user running the application, |
| 71 |
or a Denial of Service. |
| 72 |
|
| 73 |
Workaround |
| 74 |
========== |
| 75 |
|
| 76 |
There is no known workaround at this time. |
| 77 |
|
| 78 |
Resolution |
| 79 |
========== |
| 80 |
|
| 81 |
All Adobe Reader users should upgrade to the latest version: |
| 82 |
|
| 83 |
# emerge --sync |
| 84 |
# emerge --ask --oneshot --verbose ">=app-text/acroread-8.1.3" |
| 85 |
|
