Red Hat Security Advisory 2013-0589-01 - 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.

3. Description:
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.
