Ubuntu Security Notice 1197-8 - USN-1197-7 fixed a vulnerability in ca-certificates-java. The new package broke upgrades from Ubuntu 11.04 to Ubuntu 11.10. This update fixes the problem. 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. Various other issues were also addressed.
