OpenSSL SSL_OP_NETSCAPE_REUSE_CIPHER_CHANGE_BUG Ciphersuite Disabled Cipher Issue

medium Nessus Plugin ID 51893

Language:

Synopsis

The remote host allows the resumption of SSL sessions with a disabled cipher.

Description

The version of OpenSSL on the remote host has been shown to allow the use of disabled ciphers when resuming a session. This means that an attacker that sees (e.g. by sniffing) the start of an SSL connection can manipulate the OpenSSL session cache to cause subsequent resumptions of that session to use a disabled cipher chosen by the attacker.

Solution

Upgrade to OpenSSL 0.9.8j or later.
