Synopsis |
| 20 |
======== |
| 21 |
|
| 22 |
New releases of Mozilla, Epiphany, Galeon, Mozilla Thunderbird, and |
| 23 |
Mozilla Firefox fix several vulnerabilities, including remote DoS and |
| 24 |
buffer overflows. |
| 25 |
|
| 26 |
Background |
| 27 |
========== |
| 28 |
|
| 29 |
Mozilla is a popular web browser that includes a mail and newsreader. |
| 30 |
Galeon and Epiphany are both web browsers that use gecko, the Mozilla |
| 31 |
rendering engine. Mozilla Firefox is the next-generation browser from |
| 32 |
the Mozilla project that incorporates advanced features that are yet to |
| 33 |
be incorporated into Mozilla. Mozilla Thunderbird is the |
| 34 |
next-generation mail client from the Mozilla project. |

Description |
| 55 |
=========== |
| 56 |
|
| 57 |
Mozilla, Galeon, Epiphany, Mozilla Firefox and Mozilla Thunderbird |
| 58 |
contain the following vulnerabilities: |
| 59 |
|
| 60 |
* All Mozilla tools use libpng for graphics. This library contains a |
| 61 |
buffer overflow which may lead to arbitrary code execution. |
| 62 |
|
| 63 |
* If a user imports a forged Certificate Authority (CA) certificate, |
| 64 |
it may overwrite and corrupt the valid CA already installed on the |
| 65 |
machine. |
| 66 |
|
| 67 |
Mozilla, Mozilla Firefox, and other gecko-based browsers also contain a |
| 68 |
bug in their caching which may allow the SSL icon to remain visible, |
| 69 |
even when the site in question is an insecure site. |
| 70 |
|
| 71 |
Impact |
| 72 |
====== |
| 73 |
|
| 74 |
Users of Mozilla, Mozilla Firefox, and other gecko-based browsers are |
| 75 |
susceptible to SSL certificate spoofing, a Denial of Service against |
| 76 |
legitimate SSL sites, crashes, and arbitrary code execution. Users of |
| 77 |
Mozilla Thunderbird are susceptible to crashes and arbitrary code |
| 78 |
execution via malicious e-mails. |
| 79 |
|
| 80 |
Workaround |
| 81 |
========== |
| 82 |
|
| 83 |
There is no known workaround for most of these vulnerabilities. All |
| 84 |
users are advised to upgrade to the latest available version. |
| 85 |
|
| 86 |
Resolution |
| 87 |
========== |
| 88 |
|
| 89 |
All users should upgrade to the latest stable version: |
| 90 |
|
| 91 |
# emerge sync |
| 92 |
|
| 93 |
# emerge -pv your-version |
| 94 |
# emerge your-version |
| 95 |
