RHSA-2023:2319: Red Hat Security Advisory: git security and bug fix update

Gentoo Linux Security Advisory 202401-17 - A vulnerability has been found in libgit2 which could result in privilege escalation. Versions greater than or equal to 1.4.4 are affected.

Gentoo Linux Security Advisory 202312-15 - Several vulnerabilities have been found in Git, the worst of which could lead to remote code execution. Versions greater than or equal to 2.39.3 are affected.

Dell Unity 5.3 contain(s) an Arbitrary File Creation vulnerability. A remote unauthenticated attacker could potentially exploit this vulnerability by crafting arbitrary files through a request to the server.

Docker Desktop before 4.23.0 allows Access Token theft via a crafted extension icon URL. This issue affects Docker Desktop: before 4.23.0.

Docker Desktop before 4.12.0 is vulnerable to RCE via a crafted extension description or changelog. This issue affects Docker Desktop: before 4.12.0.

Progress Chef Infra Server before 15.7 allows a local attacker to exploit a /var/opt/opscode/local-mode-cache/backup world-readable temporary backup path to access sensitive information, resulting in the disclosure of all indexed node data, because OpenSearch credentials are exposed. (The data typically includes credentials for additional systems.) The attacker must wait for an admin to run the "chef-server-ctl reconfigure" command.

Related CVEs: * CVE-2022-24765: A vulnerability was found in Git. This flaw occurs due to Git not checking the ownership of directories in a local multi-user system when running commands specified in the local repository configuration. This allows the owner of the repository to cause arbitrary commands to be executed by other users who access the repository. * CVE-2022-29187: A vu...

In Docker Desktop 4.17.x the Artifactory Integration falls back to sending registry credentials over plain HTTP if the HTTPS health check has failed. A targeted network sniffing attack can lead to a disclosure of sensitive information. Only users who have Access Experimental Features enabled and have logged in to a private registry are affected.

Ubuntu Security Notice 5686-4 - USN-5686-1 fixed several vulnerabilities in Git. This update provides the corresponding fix for CVE-2022-39253 on Ubuntu 16.04 ESM. Cory Snider discovered that Git incorrectly handled certain symbolic links. An attacker could possibly use this issue to cause an unexpected behaviour.

**What type of information could be disclosed by this vulnerability?** This vulnerability could disclose sensitive information on the victim's file system as well as achieve data exfiltration.

Docker Desktop before 4.17.0 allows an attacker to execute an arbitrary command inside a Dev Environments container during initialization by tricking an user to open a crafted malicious docker-desktop:// URL.

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...

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` d...

Git for Windows is a fork of Git that contains Windows-specific patches. This vulnerability in versions prior to 2.37.1 lets Git for Windows' installer execute a binary into `C:\mingw64\bin\git.exe` by mistake. This only happens upon a fresh install, not when upgrading Git for Windows. A patch is included in version 2.37.1. Two workarounds are available. Create the `C:\mingw64` folder and remove read/write access from this folder, or disallow arbitrary authenticated users to create folders in `C:\`.

Git is a distributed revision control system. Git prior to versions 2.37.1, 2.36.2, 2.35.4, 2.34.4, 2.33.4, 2.32.3, 2.31.4, and 2.30.5, is vulnerable to privilege escalation in all platforms. An unsuspecting user could still be affected by the issue reported in CVE-2022-24765, for example when navigating as root into a shared tmp directory that is owned by them, but where an attacker could create a git repository. Versions 2.37.1, 2.36.2, 2.35.4, 2.34.4, 2.33.4, 2.32.3, 2.31.4, and 2.30.5 contain a patch for this issue. The simplest way to avoid being affected by the exploit described in the example is to avoid running git as root (or an Administrator in Windows), and if needed to reduce its use to a minimum. While a generic workaround is not possible, a system could be hardened from the exploit described in the example by removing any such repository if it exists already and creating one as root to block any future attacks.

Apple Security Advisory 2022-05-16-8 - Xcode 13.4 addresses a logic issue and a privilege escalation issue.

Git for Windows is a fork of Git containing Windows-specific patches. This vulnerability affects users working on multi-user machines, where untrusted parties have write access to the same hard disk. Those untrusted parties could create the folder `C:\.git`, which would be picked up by Git operations run supposedly outside a repository while searching for a Git directory. Git would then respect any config in said Git directory. Git Bash users who set `GIT_PS1_SHOWDIRTYSTATE` are vulnerable as well. Users who installed posh-gitare vulnerable simply by starting a PowerShell. Users of IDEs such as Visual Studio are vulnerable: simply creating a new project would already read and respect the config specified in `C:\.git\config`. Users of the Microsoft fork of Git are vulnerable simply by starting a Git Bash. The problem has been patched in Git for Windows v2.35.2. Users unable to upgrade may create the folder `.git` on all drives where Git commands are run, and remove read/write access fro...

In Docker before versions 9.03.15, 20.10.3 there is a vulnerability in which pulling an intentionally malformed Docker image manifest crashes the dockerd daemon. Versions 20.10.3 and 19.03.15 contain patches that prevent the daemon from crashing.
