USN-1197-1: Firefox and Xulrunner vulnerability
Description
It was discovered that Dutch Certificate Authority DigiNotar hadmis-issued multiple fraudulent certificates. These certificates could allowan attacker to perform a "man in the middle" (MITM) attack which would makethe user believe their connection is secure, but is actually beingmonitored. For the protection of its users, Mozilla has removed the DigiNotarcertificate. Sites using certificates issued by DigiNotar will need to seekanother certificate vendor. We are currently aware of a regression that blocks one of two Staat derNederlanden root certificates which are believed to still be secure. Thisregression is being tracked at https://launchpad.net/bugs/838322. The problem can be corrected by updating your system to the following package version: To update your system, please follow these instructions: https://wiki.ubuntu.com/Security/Upgrades. After a standard system upgrade you need to restart Firefox and anyapplications that use Xulrunner to effect the necessary changes. LP: 837557, LP: 838322
