TITLE

Git SCM  of  Git  Link interpretation vulnerabilities in products from multiple other vendors

DESCRIPTION

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`. Git SCM of Git Products from several other vendors contain link interpretation vulnerabilities.Information may be obtained. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 ==================================================================== Red Hat Security Advisory Synopsis: Moderate: git security and bug fix update Advisory ID: RHSA-2023:2319-01 Product: Red Hat Enterprise Linux Advisory URL: https://access.redhat.com/errata/RHSA-2023:2319 Issue date: 2023-05-09 CVE Names: CVE-2022-24765 CVE-2022-29187 CVE-2022-39253 CVE-2022-39260 ==================================================================== 1. Summary: An update for git is now available for Red Hat Enterprise Linux 9. Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section. 2. Relevant releases/architectures: Red Hat Enterprise Linux AppStream (v. 9) - aarch64, noarch, ppc64le, s390x, x86_64 3. As opposed to centralized version control systems with a client-server model, Git ensures that each working copy of a Git repository is an exact copy with complete revision history. This not only allows the user to work on and contribute to projects without the need to have permission to push the changes to their official repositories, but also makes it possible for the user to work with no network connection. Security Fix(es): * git: On multi-user machines Git users might find themselves unexpectedly in a Git worktree (CVE-2022-24765) * git: Bypass of safe.directory protections (CVE-2022-29187) * git: exposure of sensitive information to a malicious actor (CVE-2022-39253) * git: git shell function that splits command arguments can lead to arbitrary heap writes. (CVE-2022-39260) For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section. Additional Changes: For detailed information on changes in this release, see the Red Hat Enterprise Linux 9.2 Release Notes linked from the References section. 4. Solution: For details on how to apply this update, which includes the changes described in this advisory, refer to: https://access.redhat.com/articles/11258 5.

This update provides the corresponding updates for Ubuntu 22.10. Original advisory details: Cory Snider discovered that Git incorrectly handled certain symbolic links. An attacker could possibly use this issue to cause an unexpected behaviour. (CVE-2022-39253) Kevin Backhouse discovered that Git incorrectly handled certain command strings. An attacker could possibly use this issue to arbitrary code execution. (CVE-2022-39260) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 22.10: git 1:2.37.2-1ubuntu1.1 In general, a standard system update will make all the necessary changes. An attacker may trigger remote code execution, cause local users into executing arbitrary commands, leak information from the local filesystem, and bypass restricted shell. This update includes two changes of behavior that may affect certain setup: - It stops when directory traversal changes ownership from the current user while looking for a top-level git directory, a user could make an exception by using the new safe.directory configuration. - The default of protocol.file.allow has been changed from "always" to "user". For the stable distribution (bullseye), these problems have been fixed in version 1:2.30.2-1+deb11u1. We recommend that you upgrade your git packages. - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Gentoo Linux Security Advisory GLSA 202312-15 - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - https://security.gentoo.org/ - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Severity: High Title: Git: Multiple Vulnerabilities Date: December 27, 2023 Bugs: #838127, #857831, #877565, #891221, #894472, #905088 ID: 202312-15 - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Synopsis ======== Several vulnerabilities have been found in Git, the worst of which could lead to remote code execution.
