CVE-2014-7273
The IMAP-over-SSL implementation in getmail 4.0.0 through 4.43.0
does not verify X.509 certificates from SSL servers, which allows
man-in-the-middle attackers to spoof IMAP servers and obtain
sensitive information via a crafted certificate.

CVE-2014-7274
The IMAP-over-SSL implementation in getmail 4.44.0 does not verify
that the server hostname matches a domain name in the subject's
Common Name (CN) field of the X.509 certificate, which allows
man-in-the-middle attackers to spoof IMAP servers and obtain
sensitive information via a crafted certificate from a recognized
Certification Authority.

CVE-2014-7275
The POP3-over-SSL implementation in getmail 4.0.0 through 4.44.0
does not verify X.509 certificates from SSL servers, which allows
man-in-the-middle attackers to spoof POP3 servers and obtain
sensitive information via a crafted certificate.");
