Debian DLA-106-1 : getmail4 security update
medium Nessus Plugin ID 82090
Language:
Synopsis
The remote Debian host is missing a security update.Description
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.
NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
