More information:

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 stable distribution (wheezy), these problems have been fixed in version 4.46.0-1~deb7u1.

For the upcoming stable distribution (jessie), these problems have been fixed in version 4.46.0-1.

For the unstable distribution (sid), these problems have been fixed in version 4.46.0-1.

We recommend that you upgrade your getmail4 packages.
