Details

USN-927-1 fixed vulnerabilities in NSS on Ubuntu 9.10. This update provides the
corresponding updates for Ubuntu 9.04.

Original advisory details:

Marsh Ray and Steve Dispensa discovered a flaw in the TLS and SSLv3
protocols. If an attacker could perform a machine-in-the-middle attack at the
start of a TLS connection, the attacker could inject arbitrary content at
the beginning of the user’s session. This update adds support for the new
new renegotiation extension and will use it when the server supports it.
