Fedora 37: FEDORA-2022-fb088df94c Critical: Git Command Injection Fix

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.

Upstream update including security & bug fixes as well as feature enhancements.

From the upstream [release notes](https://raw.githubusercontent.com/git/git/v2.38.1/Documentation/RelNotes/2.30.6.txt): CVE-2022-39253 -------------- When relying on

the `--local` clone optimization, Git dereferences symbolic links in the source

repository before creating hardlinks (or copies) of the dereferenced link in the

destination repository. This can lead to surprising behavior where arbitrary

files are present in a repository's `$GIT_DIR` when cloning from a malicious

repository. Git will no longer dereference symbolic links via the `--local`

clone mechanism, and will instead refuse to clone repositories that have

symbolic links present in the `$GIT_DIR/objects` directory. Additionally, the

value of `protocol.file.allow` is changed to be "user" by default.

CVE-2022-39260 -------------- An overly-long command string given to `git

shell` can result in overflow in `split_cmdline()`, leading to arbitrary heap

writes and remote code execution when `git shell` is exposed and the directory

`$HOME/git-shell-commands` exists. `git shell` is taught to refuse interactive

commands that are longer than 4MiB in size. `split_cmdline()` is hardened to

reject inputs larger than 2GiB. Credits ------- Credit for finding
