The remote host is missing an update to curl announced via advisory USN-726-2.

The problem can be corrected by upgrading your system to the following package versions: Ubuntu 8.10: libcurl3 7.18.2-1ubuntu4.3 libcurl3-gnutls 7.18.2-1ubuntu4.3 In general, a standard system upgrade is sufficient to effect the necessary changes. https://secure1.securityspace.com/smysecure/catid.html?in=USN-726-2

USN-726-1 fixed a vulnerability in curl. Due to an incomplete fix, a regression was introduced in Ubuntu 8.10 that caused certain types of URLs to fail. This update fixes the problem. We apologize for the inconvenience. Original advisory details: It was discovered that curl did not enforce any restrictions when following URL redirects. If a user or automated system were tricked into opening a URL to an untrusted server, an attacker could use redirects to gain access to abitrary files. This update changes curl behavior to prevent following file URLs after a redirect.
