Summary
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.
