Red Hat Security Advisory 2018-2147-01

Red Hat Security Advisory 2018-2147-01
Posted Jul 10, 2018
Authored by Red Hat | Site access.redhat.com

Red Hat Security Advisory 2018-2147-01 - 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. Issues addressed include a code execution vulnerability.

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: arbitrary code execution when recursively cloning a malicious
repository (CVE-2018-11235)

* git: path sanity check in is_ntfs_dotgit() can read arbitrary memory
(CVE-2018-11233)

For more details about the security issue(s), including the impact, a CVSS
score, and other related information, refer to the CVE page(s) listed in
the References section.

4. Solution:

For details on how to apply this update, which includes the changes
described in this advisory, refer to:

https://access.redhat.com/articles/11258

5. Bugs fixed (https://bugzilla.redhat.com/):

1583862 - CVE-2018-11235 git: arbitrary code execution when recursively cloning a malicious repository
1583888 - CVE-2018-11233 git: path sanity check in is_ntfs_dotgit() can read arbitrary memory
