getmail4 - security update

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.
