USN-443-1: Firefox vulnerability
Ubuntu Security Notice USN-443-1
27th March, 2007
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 6.10
- Ubuntu 6.06 LTS
- Ubuntu 5.10
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.
The problem can be corrected by updating your system to the following package version:
- Ubuntu 6.10:
- firefox 126.96.36.199+0dfsg-0ubuntu0.6.10
- Ubuntu 6.06 LTS:
- firefox 1.5.dfsg+188.8.131.52-0ubuntu0.6.06.1
- Ubuntu 5.10:
- firefox 1.5.dfsg+184.108.40.206-0ubuntu0.5.10.1
To update your system, please follow these instructions: https://wiki.ubuntu.com/Security/Upgrades.
After a standard system upgrade you need to restart Firefox or reboot
your computer to effect the necessary changes.
