Details

USN-927-4 fixed vulnerabilities in NSS. This update provides the NSPR
needed to use the new NSS.

Original advisory details:

Marsh Ray and Steve Dispensa discovered a flaw in the TLS and SSLv3
protocols. If an attacker could perform a man 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.

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 8.04

After a standard system upgrade you need to restart any applications that
use NSPR, such as Firefox, to effect the necessary changes.
