Alpine: git: security update to 2.34.5-r0
high Tenable Cloud Security Plugin ID 404642
Description
There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:- Git is an open source, scalable, distributed revision control system. Versions prior to 2.30.6, 2.31.5,
2.32.4, 2.33.5, 2.34.5, 2.35.5, 2.36.3, and 2.37.4 are subject to exposure of sensitive information to a
malicious actor. When performing a local clone (where the source and target of the clone are on the same
volume), Git copies the contents of the source's `$GIT_DIR/objects` directory into the destination by
either creating hardlinks to the source contents, or copying them (if hardlinks are disabled via `--no-
hardlinks`). A malicious actor could convince a victim to clone a repository with a symbolic link pointing
at sensitive information on the victim's machine. This can be done either by having the victim clone a
malicious repository on the same machine, or having them clone a malicious repository embedded as a bare
repository via a submodule from any source, provided they clone with the `--recurse-submodules` option.
Git does not create symbolic links in the `$GIT_DIR/objects` directory. The problem has been patched in
the versions published on 2022-10-18, and backported to v2.30.x. Potential workarounds: Avoid cloning
untrusted repositories using the `--local` optimization when on a shared machine, either by passing the
`--no-local` option to `git clone` or cloning from a URL that uses the `file://` scheme. Alternatively,
avoid cloning repositories from untrusted sources with `--recurse-submodules` or run `git config --global
protocol.file.allow user`. (CVE-2022-39253)
- Git is an open source, scalable, distributed revision control system. `git shell` is a restricted login
shell that can be used to implement Git's push/pull functionality via SSH. In versions prior to 2.30.6,
2.31.5, 2.32.4, 2.33.5, 2.34.5, 2.35.5, 2.36.3, and 2.37.4, the function that splits the command arguments
into an array improperly uses an `int` to represent the number of entries in the array, allowing a
malicious actor to intentionally overflow the return value, leading to arbitrary heap writes. Because the
resulting array is then passed to `execv()`, it is possible to leverage this attack to gain remote code
execution on a victim machine. Note that a victim must first allow access to `git shell` as a login shell
in order to be vulnerable to this attack. This problem is patched in versions 2.30.6, 2.31.5, 2.32.4,
2.33.5, 2.34.5, 2.35.5, 2.36.3, and 2.37.4 and users are advised to upgrade to the latest version.
Disabling `git shell` access via remote logins is a viable short-term workaround. (CVE-2022-39260)
