Descriptions

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.

El comando imap-send en GIT antes de v1.8.1.4 no comprueba si el nombre del servidor coincide con un nombre de dominio en el nombre común del sujeto (CN) o el campo subjectAltName del certificado X.509, lo que permite atacantes MITM (Man-In-The-Middle) suplantar servidores SSL de su elección a través de un certificado válido.

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 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.
