    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.
