According to the versions of the git package installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :

  - A flaw was found in the way git-shell handled     command-line options for the restricted set of     git-shell commands. A remote, authenticated attacker     could use this flaw to bypass git-shell restrictions,     to view and manipulate files, by abusing the instance     of the less command launched using crafted command-line     options.(CVE-2017-8386)

  - In Git before 2.13.7, 2.14.x before 2.14.4, 2.15.x     before 2.15.2, 2.16.x before 2.16.4, and 2.17.x before     2.17.1, remote code execution can occur. With a crafted     .gitmodules file, a malicious project can execute an     arbitrary script on a machine that runs 'git clone
    --recurse-submodules' because submodule 'names' are     obtained from this file, and then appended to     $GIT_DIR/modules, leading to directory traversal with     '../' in a name. Finally, post-checkout hooks from a     submodule are executed, bypassing the intended design     in which hooks are not obtained from a remote     server.(CVE-2018-11235)

Timo Schmid of ERNW GmbH discovered that the Git git-shell, a restricted login shell for Git-only SSH access, allows a user to run an interactive pager by causing it to spawn 'git upload-pack --help'.

An issue in `git-shell` could allow remote users to run an interactive pager. From the [update announcement](https://public-inbox.org/git/xmqq8tm5ziat.fsf@gitster.mt v.corp.google.com/) :

... fix a recently disclosed problem with 'git shell', which may allow a user who comes over SSH to run an interactive pager by causing it to spawn 'git upload-pack --help' (CVE-2017-8386).

The announcement also notes :

If you are not running a server, or if your server has not been explicitly configured to use git-shell as a login shell, you are not affected. Also note that sites running 'git shell' behind gitolite are NOT vulnerable. 

Further details can be found in the commit message which fixed the issue ([3ec804490](https://github.com/git/git/commit/3ec804490)).

The remote host is affected by the vulnerability described in GLSA-201706-04 (Git: Security bypass)

    Timo Schmid discovered that the Git restricted shell incorrectly       filtered allowed commands.
  Impact :

    A remote attacker could possibly bypass security restrictions and access       sensitive information.
  Workaround :

    There is no known workaround at this time.

Security Fix(es) :

  - It was found that the git-prompt.sh script shipped with     git failed to correctly handle branch names containing     special characters. A specially crafted git repository     could use this flaw to execute arbitrary commands if a     user working with the repository configured their shell     to include repository information in the prompt.
    (CVE-2014-9938)

  - A flaw was found in the way git-shell handled     command-line options for the restricted set of git-shell     commands. A remote, authenticated attacker could use     this flaw to bypass git-shell restrictions, to view and     manipulate files, by abusing the instance of the less     command launched using crafted command-line options.
    (CVE-2017-8386)

An update for git is now available for Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.

Git is a distributed revision control system with a decentralized architecture. As opposed to centralized version control systems with a client-server model, Git ensures that each working copy of a Git repository is an exact copy with complete revision history. This not only allows the user to work on and contribute to projects without the need to have permission to push the changes to their official repositories, but also makes it possible for the user to work with no network connection.

Security Fix(es) :

* It was found that the git-prompt.sh script shipped with git failed to correctly handle branch names containing special characters. A specially crafted git repository could use this flaw to execute arbitrary commands if a user working with the repository configured their shell to include repository information in the prompt.
(CVE-2014-9938)

* A flaw was found in the way git-shell handled command-line options for the restricted set of git-shell commands. A remote, authenticated attacker could use this flaw to bypass git-shell restrictions, to view and manipulate files, by abusing the instance of the less command launched using crafted command-line options. (CVE-2017-8386)

(CVE-2017-8386)

  - A shell command injection flaw related to the handling     of ''ssh'' URLs has been discovered in Git. An attacker     could use this flaw to execute shell commands with the     privileges of the user running the Git client, for     example, when performing a ''clone'' action on a     malicious repository or a legitimate repository     containing a malicious commit.
