The imap-send command in GIT before 1.8.1.4 does not verify that the server hostname matches a domain name in the subject's Common Name (CN) or subjectAltName field of the X.509 certificate, which allows man-in-the-middle attackers to spoof SSL servers via an arbitrary valid certificate.

The remote MiracleLinux 4 host has packages installed that are affected by a vulnerability as referenced in the AXSA:2013-167:02 advisory.

    Git is a fast, scalable, distributed revision control system with an unusually rich command set that     provides both high-level operations and full access to internals.
    The git rpm installs the core tools with minimal dependencies. To install all git packages, including     tools for integrating with other SCMs, install the git-all meta-package.
    Security issues fixed with this release:
     CVE-2013-0308     The imap-send command in GIT before 1.8.1.4 does not verify that the server hostname matches a domain name     in the subject's Common Name (CN) or subjectAltName field of the X.509 certificate, which allows man-in-     the-middle attackers to spoof SSL servers via an arbitrary valid certificate.

Tenable has extracted the preceding description block directly from the MiracleLinux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

git imap-send was fixed to do SSL host verification.

This can be disabled if necessary in the config file.

The remote Mac OS X host has Apple Xcode prior to 5.0 installed. It, therefore, includes a version of git in which the imap-send command reportedly does not verify that a server hostname matches the domain name in its X.509 certificate. A man-in-the-middle attacker could leverage this vulnerability to spoof SSL servers via an arbitrary valid certificate.

The remote Oracle Linux 6 host has packages installed that are affected by a vulnerability as referenced in the ELSA-2013-0589 advisory.

Updated git packages that fix one security issue are now available for Red Hat Enterprise Linux 6.

The Red Hat Security Response Team has rated this update as having moderate security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section.

Git is a fast, scalable, distributed revision control system.

It was discovered that Git's git-imap-send command, a tool to send a collection of patches from standard input (stdin) to an IMAP folder, did not properly perform SSL X.509 v3 certificate validation on the IMAP server's certificate, as it did not ensure that the server's hostname matched the one provided in the CN field of the server's certificate. A rogue server could use this flaw to conduct man-in-the-middle attacks, possibly leading to the disclosure of sensitive information. (CVE-2013-0308)

All git users should upgrade to these updated packages, which contain a backported patch to correct this issue.
