Description

The SSLClientSocketNSS::Core::OwnAuthCertHandler function in net/socket/ssl_client_socket_nss.cc in Google Chrome before 33.0.1750.117 does not prevent changes to server X.509 certificates during renegotiations, which allows remote SSL servers to trigger use of a new certificate chain, inconsistent with the user's expectations, by initiating a TLS renegotiation.

Affected products

Google Chrome: through 33.0.1750.116; 33.0.1750.0, 33.0.1750.1, 33.0.1750.2, 33.0.1750.3, 33.0.1750.4, 33.0.1750.5 (+90)
