Description

USN-927-1 fixed vulnerabilities in nss in Ubuntu 9.10. This update provides the corresponding updates for Ubuntu 8.04 LTS.

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.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
