Ubuntu 6.06 LTS / 8.04 LTS / 8.10 / 9.04 : openssl vulnerability (USN-830-1)

Medium Nessus Plugin ID 40981

Synopsis

The remote Ubuntu host is missing one or more security-related patches.

Description

Dan Kaminsky discovered OpenSSL would still accept certificates with MD2 hash signatures. As a result, an attacker could potentially create a malicious trusted certificate to impersonate another site. This update handles this issue by completely disabling MD2 for certificate validation.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected packages.
