Security Advisory: Moderate
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
