Porter Clark. + +* for CVE-2011-3389: + SSL/TLS (wrapped and STARTTLS): fetchmail used to disable a countermeasure + against a certain kind of attack against cipher block chaining initialization + vectors (SSL_OP_DONT_INSERT_EMPTY_FRAGMENTS). + Whether this creates an exploitable situation, depends on the server and the + negotiated ciphers. + As a precaution, fetchmail 6.3.22 enables the countermeasure, by clearing + SSL_OP_DONT_INSERT_EMPTY_FRAGMENTS. + + NOTE that this can cause connections to certain non-conforming servers to + fail, in which case you can set the environment variable + FETCHMAIL_DISABLE_CBC_IV_COUNTERMEASURE to any non-empty value when starting + fetchmail to re-instate the compatibility option at the expense of security. + + Reported by Apple Product Security. + + For technical details, refer to . + See fetchmail-SA-2012-01.txt for further details. + +# BUG FIX +* The Server certificate: message in verbose mode now appears on stdout like the + remainder of the output.
