------------------------------------------------------------------------- Debian LTS Advisory DLA-3589-1 [email protected] https://www.debian.org/lts/security/ Guilhem Moulin September 29, 2023 https://wiki.debian.org/LTS
-------------------------------------------------------------------------

Package : python-git Version : 2.1.11-1+deb10u2 CVE ID : CVE-2023-41040

Santos Gallegos discovered a blind local file inclusion in python-git, a Python library to interact with Git repositories, which could lead to denial of service or potentially information disclosure.

In order to resolve some git references, python-git reads files from the .git directory but, due to improper location check, an attacker can pass a file located outside this directory thereby making python-git read arbitrary file on the system.

It remains unclear whether the attacker can gain access to actual file content, but denial of service can be achieved by passing a large or infinite file such as /dev/random.

For Debian 10 buster, this problem has been fixed in version 2.1.11-1+deb10u2.

We recommend that you upgrade your python-git packages.

For the detailed security status of python-git please refer to its security tracker page at:
