Package        : getmail4
CVE ID         : CVE-2014-7273 CVE-2014-7274 CVE-2014-7275
Debian Bug     : 766670

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.
