Debian Linux Security Advisory 2141-1 - Marsh Ray, Steve Dispensa, and Martin Rex 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 backported support for the new RFC5746 renegotiation extension which fixes this issue. If openssl is used in a server application, it will by default no longer accept renegotiation from clients that do not support the RFC5746 secure renegotiation extension. A separate advisory will add RFC5746 support for nss, the security library used by the iceweasel web browser. For apache2, there will be an update which allows to re-enable insecure renegotiation. This version of openssl is not compatible with older versions of tor. You have to use at least tor version 0.2.1.26-1~lenny+1, which has been included in the point release 5.0.7 of Debian stable.
