Background |
| 27 |
========== |
| 28 |

Description |
| 52 |
=========== |
| 53 |
|
| 54 |
Mozilla-based products are vulnerable to multiple security issues. |
| 55 |
Firstly routines handling the display of BMP images and VCards contain |
| 56 |
an integer overflow and a stack buffer overrun. Specific pages with |
| 57 |
long links, when sent using the "Send Page" function, and links with |
| 58 |
non-ASCII hostnames could both cause heap buffer overruns. |
| 59 |
|
| 60 |
Several issues were found and fixed in JavaScript rights handling: |
| 61 |
untrusted script code could read and write to the clipboard, signed |
| 62 |
scripts could build confusing grant privileges dialog boxes, and when |
| 63 |
dragged onto trusted frames or windows, JavaScript links could access |
| 64 |
information and rights of the target frame or window. Finally, |
| 65 |
Mozilla-based mail clients (Mozilla and Mozilla Thunderbird) are |
| 66 |
vulnerable to a heap overflow caused by invalid POP3 mail server |
| 67 |
responses. |
| 68 |
|
| 69 |
Impact |
| 70 |
====== |
| 71 |
|
| 72 |
An attacker might be able to run arbitrary code with the rights of the |
| 73 |
user running the software by enticing the user to perform one of the |
| 74 |
following actions: view a specially-crafted BMP image or VCard, use the |
| 75 |
"Send Page" function on a malicious page, follow links with malicious |
| 76 |
hostnames, drag multiple JavaScript links in a row to another window, |
| 77 |
or connect to an untrusted POP3 mail server. An attacker could also use |
| 78 |
a malicious page with JavaScript to disclose clipboard contents or |
| 79 |
abuse previously-given privileges to request XPI installation |
| 80 |
privileges through a confusing dialog. |
| 81 |
|
| 82 |
Workaround |
| 83 |
========== |
| 84 |
|
| 85 |
There is no known workaround covering all vulnerabilities. |
| 86 |
|
| 87 |
Resolution |
| 88 |
========== |
| 89 |
|
| 90 |
All users should upgrade to the latest stable version: |
| 91 |
|
| 92 |
# emerge sync |
| 93 |
|
| 94 |
# emerge -pv your-version |
| 95 |
# emerge your-version |
| 96 |
