Multiple vulnerabilities have been discovered in Adobe Reader: |
| 38 |
|
| 39 |
* Alin Rad Pop of Secunia Research reported a heap-based buffer |
| 40 |
overflow when processing PDF files containing a malformed JBIG2 |
| 41 |
symbol dictionary segment (CVE-2009-0193). |
| 42 |
|
| 43 |
* A buffer overflow related to a non-JavaScript function call and |
| 44 |
possibly an embedded JBIG2 image stream has been reported |
| 45 |
(CVE-2009-0658). |
| 46 |
|
| 47 |
* Tenable Network Security reported a stack-based buffer overflow |
| 48 |
that can be triggered via a crafted argument to the getIcon() method |
| 49 |
of a Collab object (CVE-2009-0927). |
| 50 |
|
| 51 |
* Sean Larsson of iDefense Labs reported a heap-based buffer overflow |
| 52 |
when processing a PDF file containing a JBIG2 stream with a size |
| 53 |
inconsistency related to an unspecified table (CVE-2009-0928). |
| 54 |
|
| 55 |
* Jonathan Brossard of the iViZ Security Research Team reported an |
| 56 |
unspecified vulnerability related to JBIG2 and input validation |
| 57 |
(CVE-2009-1061). |
| 58 |
|
| 59 |
* Will Dormann of CERT/CC reported a vulnerability lading to memory |
| 60 |

Impact |
| 63 |
====== |
| 64 |
|
| 65 |
A remote attacker could entice a user to open a specially crafted PDF |
| 66 |
document, possibly leading to the execution of arbitrary code with the |
| 67 |
privileges of the user running the application, or a Denial of Service. |
| 68 |
|
| 69 |
Workaround |
| 70 |
========== |
| 71 |
|
| 72 |
There is no known workaround at this time. |
| 73 |
|
| 74 |
Resolution |
| 75 |
========== |
| 76 |
|
| 77 |
All Adobe Reader users should upgrade to the latest version: |
| 78 |
|
| 79 |
# emerge --sync |
| 80 |
# emerge --ask --oneshot --verbose ">=app-text/acroread-8.1.4" |
| 81 |
|
