In the light of the FREAK TLS vulnerability, how may I disable insecure cipher suites manually in Safari?

A research group named SMACK has released a vulnerability known as FREAK which can be used for man-in-the-middle (MITM) attack. The vulnerability is due to an old ghost created by USA Government (NSA, more specifically) where in, years ago, they convinced several organizations to use weaker keys, known as export-grade keys for any software that was to be used outside the borders of USA. While the use of strong keys is wide spread now, several servers still have support for the weaker keys.

The group discovered that this vulnerability can be exploited by using a client and making a connection via a weak key. Once the key is generated by the server, it is reused until the server is restarted which can potentially be months. The group was able to crack this weak server key in 7.5 hours using Amazon EC2. Once this is cracked, potentially all the communication can be downgraded to use weak keys and MITM'ed.

How may I disable some or all of the insecure Cipher Suites manually by e.g. editing some configuration files in Safari manually to immediately fix the vulnerability especially in older Safari versions probably not updated by Apple?

The Cipher Suites in question are:

CipherSuite TLS_RSA_EXPORT_WITH_RC4_40_MD5         = { 0x00,0x03};
CipherSuite TLS_RSA_EXPORT_WITH_RC2_CBC_40_MD5     = { 0x00,0x06};
CipherSuite TLS_RSA_EXPORT_WITH_DES40_CBC_SHA      = { 0x00,0x08};
CipherSuite TLS_DH_DSS_EXPORT_WITH_DES40_CBC_SHA   = { 0x00,0x0B};
CipherSuite TLS_DH_RSA_EXPORT_WITH_DES40_CBC_SHA   = { 0x00,0x0E};
CipherSuite TLS_DHE_DSS_EXPORT_WITH_DES40_CBC_SHA  = { 0x00,0x11};
CipherSuite TLS_DHE_RSA_EXPORT_WITH_DES40_CBC_SHA  = { 0x00,0x14};
CipherSuite TLS_DH_anon_EXPORT_WITH_RC4_40_MD5     = { 0x00,0x17};
CipherSuite TLS_DH_anon_EXPORT_WITH_DES40_CBC_SHA  = { 0x00,0x19};
