Package        : python-git
Version        : 3.1.14-1+deb11u1
CVE ID         : CVE-2022-24439 CVE-2023-40267 CVE-2023-41040
Debian Bug     : 1027163 1043503

GitPython provides object model access to a Git repository.

CVE-2022-24439, CVE-2023-40267 (follow-up)

    Remote Code Execution (RCE) is possible due to improper user input
    validation, which makes it possible to inject a maliciously crafted
    remote URL into the clone command. Exploiting this vulnerability is
    possible because the library makes external calls to git without
    sufficient sanitization of input arguments.

CVE-2023-41040

    GitPython reads files from the `.git` directory, in some places the
    name of the file being read is provided by the user, GitPython
    doesn't check if this file is located outside the `.git` directory.
    This allows an attacker to make GitPython read any file from the
    system.

For Debian 11 bullseye, these problems have been fixed in version
3.1.14-1+deb11u1.

We recommend that you upgrade your python-git packages.
