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.

Xcode 5.0 is now available and addresses a security issue in Git. When using the imap-send command, git did not verify that the server hostname matched a domain name in the X.509 certificate, which allowed a man-in-the-middle attacker to spoof SSL servers via an arbitrary valid certificate. This issue was addressed by updating git to version 1.8.3.1.
