"Several vulnerabilities have been discovered in getmail4, a mail
retriever with support for POP3, IMAP4 and SDPS, that could allow
man-in-the-middle attacks.

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.

For the squeeze distribution, those problems have been fixed by
importing a new upstream version: 4.46.0-1~deb6u1. The updated package
has been prepared by Osamu Aoki.
