ca-certificates-java vulnerability

A security issue affects these releases of Ubuntu and its derivatives:

  • Ubuntu 11.10
  • Ubuntu 11.04
  • Ubuntu 10.10
  • Ubuntu 10.04 LTS


A certificate authority mis-issued fraudulent certificates.

Software Description

  • ca-certificates-java - Common CA certificates (JKS keystore)


USN-1197-5 addressed an issue in ca-certificates pertaining to the Dutch Certificate Authority DigiNotar mis-issuing fraudulent certificates. This update provides the corresponding update for ca-certificates-java.

Original advisory details:

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.
