Zusammenfassung:	Ubuntu Update for Linux kernel vulnerabilities USN-1238-2
Beschreibung:	Summary: Ubuntu Update for Linux kernel vulnerabilities USN-1238-2 Vulnerability Insight: USN-1238-1 fixed vulnerabilities in Puppet. The upstream patch introduced a regression in Ubuntu 11.04 when executing certain commands. This update fixes the problem. We apologize for the inconvenience. Original advisory details: It was discovered that Puppet incorrectly handled the non-default 'certdnsnames' option when generating certificates. If this setting was added to puppet.conf, the puppet master's DNS alt names were added to the X.509 Subject Alternative Name field of all certificates, not just the puppet master's certificate. An attacker that has an incorrect agent certificate in his possession can use it to impersonate the puppet master in a man-in-the-middle attack. Affected Software/OS: puppet on Ubuntu 11.04 Solution: Please Install the Updated Packages. CVSS Score: 2.6 CVSS Vector: AV:N/AC:H/Au:N/C:N/I:P/A:N
