Firefox vulnerability

Releases

Details

A flaw was discovered in how Firefox handled PASV FTP responses. If a
user were tricked into visiting a malicious FTP server, a remote
attacker could perform a port-scan of machines within the user's
network, leading to private information disclosure.

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 6.10
  • firefox - 2.0.0.3+0dfsg-0ubuntu0.6.10
Ubuntu 6.06
  • firefox - 1.5.dfsg+1.5.0.11-0ubuntu0.6.06.1
Ubuntu 5.10
  • firefox - 1.5.dfsg+1.5.0.11-0ubuntu0.5.10.1

After a standard system upgrade you need to restart Firefox or reboot
your computer to effect the necessary changes.
