Alpine: git: security update to 2.38.4-r0

high Tenable Self-Hosted Container Security Plugin ID 404655

Description

There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

 - Git is a revision control system. Using a specially-crafted repository, Git prior to versions 2.39.2,
 2.38.4, 2.37.6, 2.36.5, 2.35.7, 2.34.7, 2.33.7, 2.32.6, 2.31.7, and 2.30.8 can be tricked into using its
 local clone optimization even when using a non-local transport. Though Git will abort local clones whose
 source `$GIT_DIR/objects` directory contains symbolic links, the `objects` directory itself may still be a
 symbolic link. These two may be combined to include arbitrary files based on known paths on the victim's
 filesystem within the malicious repository's working copy, allowing for data exfiltration in a similar
 manner as CVE-2022-39253. A fix has been prepared and will appear in v2.39.2 v2.38.4 v2.37.6 v2.36.5
 v2.35.7 v2.34.7 v2.33.7 v2.32.6, v2.31.7 and v2.30.8. If upgrading is impractical, two short-term
 workarounds are available. Avoid cloning repositories from untrusted sources with `--recurse-submodules`.
 Instead, consider cloning repositories without recursively cloning their submodules, and instead run `git
 submodule update` at each layer. Before doing so, inspect each new `.gitmodules` file to ensure that it
 does not contain suspicious module URLs. (CVE-2023-22490)

 - Git, a revision control system, is vulnerable to path traversal prior to versions 2.39.2, 2.38.4, 2.37.6,
 2.36.5, 2.35.7, 2.34.7, 2.33.7, 2.32.6, 2.31.7, and 2.30.8. By feeding a crafted input to `git apply`, a
 path outside the working tree can be overwritten as the user who is running `git apply`. A fix has been
 prepared and will appear in v2.39.2, v2.38.4, v2.37.6, v2.36.5, v2.35.7, v2.34.7, v2.33.7, v2.32.6,
 v2.31.7, and v2.30.8. As a workaround, use `git apply --stat` to inspect a patch before applying; avoid
 applying one that creates a symbolic link and then creates a file beyond the symbolic link.
