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.

Comment 1 Jan Lieskovsky 2010-12-23 14:46:25 UTC

This issue affects the versions of the offlineimap package, as shipped
with Fedora release of 13 and 14.

Please schedule an update with the above patch.

Note: OfflineIMAP v6.3.1 was also released:
      [1] http://permalink.gmane.org/gmane.mail.imap.offlineimap.general/2138
     
      but didn't check if it contains the change already.
