Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
Multiple vulnerabilities have been identified, the worst of which allow |
| 19 |
arbitrary code execution on a user's system via a malicious Flash file. |
| 20 |
|
| 21 |
Background |
| 22 |
========== |
| 23 |
|
| 24 |
The Adobe Flash Player is a renderer for the popular SWF file format, |
| 25 |
which is commonly used to provide interactive websites, digital |
| 26 |
experiences and mobile content. |

Description |
| 37 |
=========== |
| 38 |
|
| 39 |
Multiple vulnerabilities have been discovered in Adobe Flash: |
| 40 |
|
| 41 |
* Secunia Research and Zero Day Initiative reported a boundary error |
| 42 |
related to DeclareFunction2 Actionscript tags in SWF files |
| 43 |
(CVE-2007-6019). |
| 44 |
|
| 45 |
* The ISS X-Force and the Zero Day Initiative reported an unspecified |
| 46 |
input validation error that might lead to a buffer overflow |
| 47 |
(CVE-2007-0071). |
| 48 |
|
| 49 |
* Microsoft, UBsecure and JPCERT/CC reported that cross-domain policy |
| 50 |
files are not checked before sending HTTP headers to another domain |
| 51 |
(CVE-2008-1654) and that it does not sufficiently restrict the |
| 52 |
interpretation and usage of cross-domain policy files |
| 53 |
(CVE-2007-6243). |
| 54 |
|
| 55 |
* The Stanford University and Ernst and Young's Advanced Security |
| 56 |
Center reported that Flash does not pin DNS hostnames to a single IP |
| 57 |
addresses, allowing for DNS rebinding attacks (CVE-2007-5275, |
| 58 |
CVE-2008-1655). |
| 59 |
|
| 60 |
* The Google Security Team and Minded Security Multiple reported |
| 61 |
multiple cross-site scripting vulnerabilities when passing input to |
| 62 |
Flash functions (CVE-2007-6637). |
| 63 |
|
| 64 |
Impact |
| 65 |
====== |
| 66 |
|
| 67 |
A remote attacker could entice a user to open a specially crafted file |
| 68 |
(usually in a web browser), possibly leading to the execution of |
| 69 |
arbitrary code with the privileges of the user running the Adobe Flash |
| 70 |
Player. The attacker could also cause a user's machine to send HTTP |
| 71 |
requests to other hosts, establish TCP sessions with arbitrary hosts, |
| 72 |
bypass the security sandbox model, or conduct Cross-Site Scripting and |
| 73 |
Cross-Site Request Forgery attacks. |
| 74 |
|
| 75 |
Workaround |
| 76 |
========== |
| 77 |
|
| 78 |
There is no known workaround at this time. |
| 79 |
|
| 80 |
Resolution |
| 81 |
========== |
| 82 |
|
| 83 |
All Adobe Flash Player users should upgrade to the latest version: |
| 84 |
|
| 85 |
# emerge --sync |
| 86 |
# emerge --ask --oneshot -v ">=net-www/netscape-flash-9.0.124.0" |
| 87 |
