Synopsis |
17 |
======== |
18 |
|
19 |
Multiple vulnerabilities have been identified, the worst of which allow |
20 |
arbitrary code execution on a user's system via a malicious Flash file. |
21 |
|
22 |
Background |
23 |
========== |
24 |
|
25 |
The Adobe Flash Player is a renderer for the popular SWF file format, |
26 |
which is commonly used to provide interactive websites, digital |
27 |
experiences and mobile content. |

Description |
38 |
=========== |
39 |
|
40 |
* Flash contains a copy of PCRE which is vulnerable to a heap-based |
41 |
buffer overflow (GLSA 200711-30, CVE-2007-4768). |
42 |
|
43 |
* Aaron Portnoy reported an unspecified vulnerability related to |
44 |
input validation (CVE-2007-6242). |
45 |
|
46 |
* Jesse Michael and Thomas Biege reported that Flash does not |
47 |
correctly set memory permissions (CVE-2007-6246). |
48 |
|
49 |
* Dan Boneh, Adam Barth, Andrew Bortz, Collin Jackson, and Weidong |
50 |
Shao reported that Flash does not pin DNS hostnames to a single IP |
51 |
addresses, allowing for DNS rebinding attacks (CVE-2007-5275). |
52 |
|
53 |
* David Neu reported an error withing the implementation of the |
54 |
Socket and XMLSocket ActionScript 3 classes (CVE-2007-4324). |
55 |
|
56 |
* Toshiharu Sugiyama reported that Flash does not sufficiently |
57 |
restrict the interpretation and usage of cross-domain policy files, |
58 |
allowing for easier cross-site scripting attacks (CVE-2007-6243). |
59 |
|
60 |
* Rich Cannings reported a cross-site scripting vulnerability in the |
61 |
way the "asfunction:" protocol was handled (CVE-2007-6244). |
62 |
|
63 |
* Toshiharu Sugiyama discovered that Flash allows remote attackers to |
64 |
modify HTTP headers for client requests and conduct HTTP Request |
65 |
Splitting attacks (CVE-2007-6245). |
66 |
|
67 |
Impact |
68 |
====== |
69 |
|
70 |
A remote attacker could entice a user to open a specially crafted file |
71 |
(usually in a web browser), possibly leading to the execution of |
72 |
arbitrary code with the privileges of the user running the Adobe Flash |
73 |
Player. The attacker could also cause a user's machine to establish TCP |
74 |
sessions with arbitrary hosts, bypass the Security Sandbox Model, |
75 |
obtain sensitive information, port scan arbitrary hosts, or conduct |
76 |
cross-site-scripting attacks. |
77 |
|
78 |
Workaround |
79 |
========== |
80 |
|
81 |
There is no known workaround at this time. |
82 |
|
83 |
Resolution |
84 |
========== |
85 |
|
86 |
All Adobe Flash Player users should upgrade to the latest version: |
87 |
|
88 |
# emerge --sync |
89 |
# emerge --ask --oneshot --verbose ">=net-www/netscape-flash-9.0.115.0" |
90 |
|
91 |
Please be advised that unaffected packages of the Adobe Flash Player |
92 |
have known problems when used from within the Konqueror and Opera |
93 |
browsers. |
