Ubuntu Update for Linux kernel vulnerabilities USN-1197-1
Please Install the Updated Packages.
It was discovered that Dutch Certificate Authority DigiNotar, had mis-issued multiple fraudulent certificates. These certificates could allow an attacker to perform a " man in the middle" (MITM) attack which would make the user believe their connection is secure, but is actually being monitored. For the protection of its users, Mozilla has removed the DigiNotar certificate. Sites using certificates issued by DigiNotar will need to seek another certificate vendor. We are currently aware of a regression that blocks one of two Staat der Nederlanden root certificates which are believed to still be secure. This regression is being tracked at https://launchpad.net/bugs/838322
