Description Josh Bressers 2006-04-13 04:01:37 UTC

Privilege escalation using a JavaScript function's cloned parent


shutdown discovered it was possible to use the Object.watch() method to
access an internal function object (the "clone parent") which could then be
used to run arbitrary JavaScript code with full permission. This could be
used to install malware such as password sniffers or viruses.

In pre-release versions of Firefox 1.5 the same technique could be applied
to the Array generic methods introduced in that release.

Note: Thunderbird shares the JavaScript engine with Firefox and could be
vulnerable if JavaScript were to be enabled in mail. This is not the default
setting and we strongly discourage users from running JavaScript in mail.

Workaround

Disable JavaScript until you can upgrade to a fixed version.

Lifting embargo

Comment 2 Matěj Cepl 2007-07-18 17:28:53 UTC

Fedora Core 5 is no longer supported, could you please reproduce this with the
updated version of the currently supported distribution (Fedora Core 6, or
Fedora 7, or Rawhide)? If this issue turns out to still be reproducible, please
let us know in this bug report.  If after a month's time we have not heard back
from you, we will have to close this bug as CANTFIX.

Setting status to NEEDINFO, and awaiting information from the reporter.

Thanks in advance.

Comment 3 Matěj Cepl 2007-08-28 14:38:49 UTC

We haven't got any reply to the last question about reproducability of the bug
with Fedora Core 6, Fedora 7, or Fedora devel. Mass closing this bug, so if you
have new information that would help us fix this bug, please reopen it with the
additional information.
