Matthias Andree reports :

Fetchmail version 6.3.9 enabled ‘all SSL workarounds’ (SSL_OP_ALL) which contains a switch to disable a countermeasure against certain attacks against block ciphers that permit guessing the initialization vectors, providing that an attacker can make the application (fetchmail) encrypt some data for him – which is not easily the case.

Stream ciphers (such as RC4) are unaffected.
