According to the versions of the python3 packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :
An issue was found in the CPython `tempfile.TemporaryDirectory` class affecting versions 3.12.1, 3.11.7, 3.10.13, 3.9.18, and 3.8.18 and prior.The tempfile.TemporaryDirectory class would dereference symlinks during cleanup of permissions-related errors. This means users which can run privileged programs are potentially able to modify permissions of files referenced by symlinks in some circumstances.(CVE-2023-6597)
An issue was found in the CPython `zipfile` module affecting versions 3.12.1, 3.11.7, 3.10.13, 3.9.18, and 3.8.18 and prior.The zipfile module is vulnerable to quoted-overlap zip-bombs which exploit the zip format to create a zip-bomb with a high compression ratio. The fixed versions of CPython makes the zipfile module reject zip archives which overlap entries in the archive.(CVE-2024-0450)
Tenable has extracted the preceding description block directly from the EulerOS python3 security advisory.
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
