Integer overflow in Git before 2.7.4 allows remote attackers to execute arbitrary code via a (1) long filename or (2) many nested trees, which triggers a heap-based buffer overflow.

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

  - 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)

  - 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.(CVE-2017-1000117)

  - Git before 2.10.5, 2.11.x before 2.11.4, 2.12.x before     2.12.5, 2.13.x before 2.13.6, and 2.14.x before 2.14.2     uses unsafe Perl scripts to support subcommands such as     cvsserver, which allows attackers to execute arbitrary     OS commands via shell metacharacters in a module name.
    The vulnerable code is reachable via git-shell even     without CVS support.(CVE-2017-14867)

  - 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)

  - An integer truncation flaw and an integer overflow     flaw, both leading to a heap-based buffer overflow,     were found in the way Git processed certain path     information. A remote attacker could create a specially     crafted Git repository that would cause a Git client or     server to crash or, possibly, execute arbitrary     code.(CVE-2016-2324)

  - A flaw was found in the way the git-remote-ext helper     processed certain URLs. If a user had Git configured to     automatically clone submodules from untrusted     repositories, an attacker could inject commands into     the URL of a submodule, allowing them to execute     arbitrary code on the user's system.(CVE-2015-7545)

  - Git before 2.14.5, 2.15.x before 2.15.3, 2.16.x before     2.16.5, 2.17.x before 2.17.2, 2.18.x before 2.18.1, and     2.19.x before 2.19.1 allows remote code execution     during processing of a recursive 'git clone' of a     superproject if a .gitmodules file has a URL field     beginning with a '-' character.(CVE-2018-17456)

  - An integer truncation flaw and an integer overflow     flaw, both leading to a heap-based buffer overflow,     were found in the way Git processed certain path     information. A remote attacker could create a specially     crafted Git repository that would cause a Git client or     server to crash or, possibly, execute arbitrary     code.(CVE-2016-2315)

The version of Apple Xcode installed on the remote Mac OS X host is prior to 7.3.1. It is, therefore, affected by multiple remote code execution vulnerabilities in the bundled version of Git due to overflow conditions in the path_name() function in revision.c that are triggered when pushing or cloning a repository with a large filename or containing a large number of nested trees. A remote attacker can exploit these issues to cause a heap-based buffer overflow, resulting in the execution of arbitrary code.

The remote host is affected by the vulnerability described in GLSA-201605-01 (Git: Multiple vulnerabilities)

    Git is vulnerable to the remote execution of arbitrary code by cloning       repositories with large filenames or a large number of nested trees.
      Additionally, some protocols within Git, such as git-remote-ext, can       execute arbitrary code found within URLs. These URLs that submodules use       may come from arbitrary sources (e.g., .gitmodules files in a remote       repository), and can effect those who enable recursive fetch. Restrict       the allowed protocols to well known and safe ones.
  Impact :

    Remote attackers could execute arbitrary code on both client and server.
  Workaround :

    There is no known workaround at this time.

Updated git packages that fix two security issues are now available for Red Hat Enterprise Linux 6 and 7.

Red Hat Product Security has rated this update as having Important security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links 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.
