1. Summary:
An update for git is now available for Red Hat Enterprise Linux 7.7
Extended Update Support.
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 ComputeNode Optional EUS (v. 7.7) - noarch, x86_64
Red Hat Enterprise Linux Server EUS (v. 7.7) - noarch, ppc64, ppc64le, s390x, x86_64
Red Hat Enterprise Linux Server Optional EUS (v. 7.7) - noarch, ppc64, 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.
Security Fix(es):
* git: Crafted URL containing new lines can cause credential leak
(CVE-2020-5260)
* git: Crafted URL containing new lines, empty host or lacks a scheme can
cause credential leak (CVE-2020-11008)
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.
