openSUSE 15 Security Update : python-GitPython (openSUSE-SU-2023:0271-1)

medium Nessus Plugin ID 181920

Language:

Synopsis

The remote openSUSE host is missing a security update.

Description

The remote openSUSE 15 host has a package installed that is affected by a vulnerability as referenced in the openSUSE- SU-2023:0271-1 advisory.

 - GitPython is a python library used to interact with Git repositories. In order to resolve some git references, 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. This vulnerability is present in https://github.com/gitpython- developers/GitPython/blob/1c8310d7cae144f74a671cbe17e51f63a830adbf/git/refs/symbolic.py#L174-L175. That code joins the base directory with a user given string without checking if the final path is located outside the base directory. This vulnerability cannot be used to read the contents of files but could in theory be used to trigger a denial of service for the program. This issue has not yet been addressed.
 (CVE-2023-41040)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected python3-GitPython package.
