Description |
| 40 |
=========== |
| 41 |
|
| 42 |
The following vulnerabilities were found and fixed in Mozilla |
| 43 |
Thunderbird: |
| 44 |
|
| 45 |
* Mark Dowd from ISS X-Force reported an exploitable heap overrun in |
| 46 |
the GIF processing of obsolete Netscape extension 2 (CAN-2005-0399) |
| 47 |
|
| 48 |
* Daniel de Wildt and Gael Delalleau discovered a memory overwrite in |
| 49 |
a string library (CAN-2005-0255) |
| 50 |
|
| 51 |
* Wind Li discovered a possible heap overflow in UTF8 to Unicode |
| 52 |
conversion (CAN-2005-0592) |
| 53 |
|
| 54 |
* Phil Ringnalda reported a possible way to spoof Install source with |
| 55 |
user:pass@host (CAN-2005-0590) |
| 56 |
|
| 57 |
Impact |
| 58 |
====== |
| 59 |
|
| 60 |
The GIF heap overflow could be triggered by a malicious GIF image that |
| 61 |
would end up executing arbitrary code with the rights of the user |
| 62 |
running Thunderbird. The other overflow issues, while not thought to be |
| 63 |
exploitable, would have the same impact. Furthermore, by setting up |
| 64 |
malicious websites and convincing users to follow untrusted links, |
| 65 |
attackers may leverage the spoofing issue to trick user into installing |
| 66 |
malicious extensions. |
| 67 |
|
| 68 |
Workaround |
| 69 |
========== |
| 70 |
|
| 71 |
There is no known workaround at this time. |
| 72 |
|
| 73 |
Resolution |
| 74 |
========== |
| 75 |

| 80 |
">=mail-client/mozilla-thunderbird-1.0.2" |
| 81 |
|
| 82 |
All Mozilla Thunderbird binary users should upgrade to the latest |
| 83 |
version: |
| 84 |
|
| 85 |
# emerge --sync |
| 86 |
# emerge --ask --oneshot --verbose |
| 87 |
