Description Jan Lieskovsky 2010-12-23 14:24:29 UTC 
OfflineIMAP prior commit:
[1] https://github.com/nicolas33/offlineimap/commit/4f57b94e2333c37c5a7251fc88dfeda9bc0b226a

did not perform SSL server certificate validation,
even when "ssl = yes" option was specified in the
configuration file. If an attacker was able to get 
a carefully-crafted certificate signed by a 
Certificate Authority trusted by OfflineIMAP, 
the attacker could use the certificate during a 
man-in-the-middle attack and potentially confuse 
OfflineIMAP into accepting it by mistake.
