Name : git
Product : Fedora 27
Version : 2.14.4
Release : 1.fc27
URL : https://git-scm.com/
Summary : Fast Version Control System
Description :
Git is a fast, scalable, distributed revision control system with an
unusually rich command set that provides both high-level operations
and full access to internals.

The git rpm installs common set of tools which are usually using with
small amount of dependencies. To install all git packages, including
tools for integrating with other SCMs, install the git-all meta-package.

Update Information:

Upstream security fixes related to .gitmodules handling. From the [upstream
announcement](https://public-inbox.org/git/xmqqy3g2flb6.fsf@gitster-
ct.c.googlers.com/): ``` * Submodule "names" come from the untrusted
.gitmodules file, but we blindly append them to $GIT_DIR/modules to create
our
on-disk repo paths. This means you can do bad things by putting "../"
into the
name. We now enforce some rules for submodule names which will cause Git to
ignore these malicious names (CVE-2018-11235). Credit for finding this
vulnerability and the proof of concept from which the test script was adapted
goes to Etienne Stalmans. * It was possible to trick the code that sanity-
checks paths on NTFS into reading random piece of memory (CVE-2018-11233).
```
Also fix a segfault in rev-parse with invalid input (#1581678) and install
contrib/diff-highlight (#1550251).
