FreeBSD : fetchmail -- chosen plaintext attack against SSL CBC initialization vectors (18ce9a90-f269-11e1-be53-080027ef73ec) (BEAST)

Medium Nessus Plugin ID 61725


The remote FreeBSD host is missing a security-related update.


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.

Credits to Apple Product Security for reporting this.


Update the affected package.
