Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
A vulnerability has been identified that allows arbitrary code |
| 19 |
execution on a user's system via the handling of malicious SWF files. |
| 20 |
|
| 21 |
Background |
| 22 |
========== |
| 23 |
|
| 24 |
The Macromedia Flash Player is a renderer for the popular SWF filetype |
| 25 |
which is commonly used to provide interactive websites, digital |
| 26 |
experiences and mobile content. |
| 27 |
|
| 28 |
Affected packages |
| 29 |
================= |
| 30 |
|
| 31 |
------------------------------------------------------------------- |
| 32 |
Package / Vulnerable / Unaffected |
| 33 |
------------------------------------------------------------------- |
| 34 |
1 net-www/netscape-flash < 7.0.61 >= 7.0.61 |
| 35 |
|
| 36 |
Description |
| 37 |
=========== |
| 38 |
|
| 39 |
When handling a SWF file, the Macromedia Flash Player incorrectly |
| 40 |
validates the frame type identifier stored in the SWF file which is |
| 41 |
used as an index to reference an array of function pointers. A |
| 42 |
specially crafted SWF file can cause this index to reference memory |
| 43 |
outside of the scope of the Macromedia Flash Player, which in turn can |
| 44 |
cause the Macromedia Flash Player to use unintended memory address(es) |
| 45 |
as function pointers. |
| 46 |
|
| 47 |
Impact |
| 48 |
====== |
| 49 |
|
| 50 |
An attacker serving a maliciously crafted SWF file could entice a user |
| 51 |
to view the SWF file and execute arbitrary code on the user's machine. |
| 52 |
|
| 53 |
Workaround |
| 54 |
========== |
| 55 |
|
| 56 |
There is no known workaround at this time. |
| 57 |
|
| 58 |
Resolution |
| 59 |
========== |
| 60 |
|
| 61 |
All Macromedia Flash Player users should upgrade to the latest version: |
| 62 |
|
| 63 |
# emerge --sync |
| 64 |
# emerge --ask --oneshot --verbose ">=net-www/netscape-flash-7.0.61" |
| 65 |
