Fedora 32: 2021-ffd0b2108d Moderate: Git Remote Execution

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.

Security fix for CVE-2021-21300 A specially crafted repository that contains

symbolic links as well as files using a clean/smudge filter such as Git LFS, may

cause just-checked out script to be executed while cloning onto a case-insensitive file system such as NTFS, HFS+ or APFS. Note that clean/smudge

filters have to be configured in advance, in the system-wide or global user

configuration for this bug to be exploited. This issue does not affect Fedora

in default configurations. For further details, please refer to the [upstream

advisory](https://github.com/git/git/security/advisories/GHSA-8prw-h3cq-mghm).
