    Advisory ID:       RHSA-2019:4356-01
    Product:           Red Hat Enterprise Linux
    Advisory URL:      https://access.redhat.com/errata/RHSA-2019:4356
    Issue date:        2019-12-19
    CVE Names:         CVE-2019-1348 CVE-2019-1349 CVE-2019-1352 
                       CVE-2019-1387 
    =====================================================================
    
    1. Summary:
    
    An update for git is now available for Red Hat Enterprise Linux 8.
    
    Red Hat Product Security has rated this update as having a security impact
    of Important. 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.
    
    2. Relevant releases/architectures:
    
    Red Hat Enterprise Linux AppStream (v. 8) - aarch64, noarch, ppc64le, s390x, x86_64
    
    3. Description:
    
    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.
    
    The following packages have been upgraded to a later upstream version: git
    (2.18.2). (BZ#1784058)
    
    Security Fix(es):
    
    * git: Remote code execution in recursive clones with nested submodules
    (CVE-2019-1387)
    
    * git: Arbitrary path overwriting via export-marks in-stream command
    feature (CVE-2019-1348)
    
    * git: Recursive submodule cloning allows using git directory twice with
    synonymous directory name written in .git/ (CVE-2019-1349)
    
    * git: Files inside the .git directory may be overwritten during cloning
    via NTFS Alternate Data Streams (CVE-2019-1352)
    
    For more details about the security issue(s), including the impact, a CVSS
    score, acknowledgments, and other related information, refer to the CVE
    page(s) listed in the References section.
