The remote host is missing an update to firefox
announced via advisory USN-546-2.
A security issue affects the following Ubuntu releases:
Ubuntu 6.10
Ubuntu 7.04
Ubuntu 7.10
This advisory also applies to the corresponding versions of
Kubuntu, Edubuntu, and Xubuntu.
USN-546-1 fixed vulnerabilities in Firefox. The upstream update included
a faulty patch which caused the drawImage method of the canvas element to
fail. This update fixes the problem.
We apologize for the inconvenience.
Original advisory details:
It was discovered that Firefox incorrectly associated redirected sites
as the origin of jar: contents. A malicious web site could exploit this
to modify or steal confidential data (such as passwords) from other web
sites. (CVE-2007-5947)
Various flaws were discovered in the layout and JavaScript engines. By
tricking a user into opening a malicious web page, an attacker could
execute arbitrary code with the user's privileges. (CVE-2007-5959)
Gregory Fleischer discovered that it was possible to use JavaScript to
manipulate Firefox's Referer header. A malicious web site could exploit
this to conduct cross-site request forgeries against sites that relied
only on Referer headers for protection from such attacks. (CVE-2007-5960)
Solution:
The problem can be corrected by upgrading your system to the
following package versions:
Ubuntu 6.10:
firefox 2.0.0.11+0nobinonly-0ubuntu0.6.10
Ubuntu 7.04:
firefox 2.0.0.11+1nobinonly-0ubuntu0.7.4
Ubuntu 7.10:
firefox 2.0.0.11+2nobinonly-0ubuntu0.7.10
After a standard system upgrade you need to restart Firefox to effect
the necessary changes.
