Description |
| 42 |
=========== |
| 43 |
|
| 44 |
Tom Ferris reported a heap-based buffer overflow involving wide SVG |
| 45 |
stroke widths that affects Mozilla Firefox 2 only. Various researchers |
| 46 |
reported some errors in the JavaScript engine potentially leading to |
| 47 |
memory corruption. Mozilla Firefox also contains minor vulnerabilities |
| 48 |
involving cache collision and unsafe pop-up restrictions, filtering or |
| 49 |
CSS rendering under certain conditions. |
| 50 |
|
| 51 |
Impact |
| 52 |
====== |
| 53 |
|
| 54 |
An attacker could entice a user to view a specially crafted web page |
| 55 |
that will trigger one of the vulnerabilities, possibly leading to the |
| 56 |
execution of arbitrary code. It is also possible for an attacker to |
| 57 |
spoof the address bar, steal information through cache collision, |
| 58 |
bypass the local files protection mechanism with pop-ups, or perform |
| 59 |
cross-site scripting attacks, leading to the exposure of sensitive |
| 60 |
information, like user credentials. |
| 61 |
|
| 62 |
Workaround |
| 63 |
========== |
| 64 |
|
| 65 |
There is no known workaround at this time for all of these issues, but |
| 66 |
most of them can be avoided by disabling JavaScript. |
| 67 |
|
| 68 |
Resolution |
| 69 |
========== |
| 70 |
|
| 71 |
Users upgrading to the following releases of Mozilla Firefox should |
| 72 |
note that this upgrade has been found to lose the saved passwords file |
| 73 |
in some cases. The saved passwords are encrypted and stored in the |
| 74 |
'signons.txt' file of ~/.mozilla/ and we advise our users to save that |
| 75 |
file before performing the upgrade. |
| 76 |
|
| 77 |
All Mozilla Firefox 1.5 users should upgrade to the latest version: |
| 78 |
|
| 79 |
# emerge --sync |
| 80 |
# emerge --ask --oneshot --verbose ">=www-client/mozilla-firefox-1.5.0.10" |
| 81 |
|
| 82 |
All Mozilla Firefox 1.5 binary users should upgrade to the latest |
| 83 |
version: |
| 84 |
|
| 85 |
# emerge --sync |
| 86 |
# emerge --ask --oneshot --verbose ">=www-client/mozilla-firefox-bin-1.5.0.10" |
| 87 |
|
| 88 |
All Mozilla Firefox 2.0 users should upgrade to the latest version: |
| 89 |
|
| 90 |
# emerge --sync |
| 91 |
# emerge --ask --oneshot --verbose ">=www-client/mozilla-firefox-2.0.0.2" |
| 92 |
|
| 93 |
All Mozilla Firefox 2.0 binary users should upgrade to the latest |
| 94 |
version: |
| 95 |
|
| 96 |
# emerge --sync |
| 97 |
# emerge --ask --oneshot --verbose ">=www-client/mozilla-firefox-bin-2.0.0.2" |
