DescriptionA flaw was found in libgit2, a cross-platform, linkable library implementation of Git. When using an SSH remote with the optional libssh2 backend, libgit2 does not perform certificate checking by default. Prior versions of libgit2 require the caller to set the `certificate_check` field of libgit2's `git_remote_callbacks` structure. If a certificate check callback is not set, libgit2 does not perform any certificate checking. This means that by default, without configuring a certificate check callback, clients will not perform validation on the server SSH keys and may be subject to a Man-in-the-middle attack.A flaw was found in libgit2, a cross-platform, linkable library implementation of Git.

Unless explicitly stated as not affected, all previous versions of packages in any minor update stream of a product listed here should be assumed vulnerable, although may not have been subject to full analysis.
