"The version of Tencent Linux installed on the remote TencentOS Server 3 host is prior to tested version. It is,
therefore, affected by multiple vulnerabilities as referenced in the TSSA-2024:1116 advisory.

    Package updates are available for TencentOS Server 3 that fix the following vulnerabilities:

    CVE-2024-9287:
    A vulnerability has been found in the CPython venv module and CLI where path names provided when creating
    a virtual environment were not quoted properly, allowing the creator to inject commands into virtual
    environment activation scripts (ie source venv/bin/activate). This means that attacker-controlled
    virtual environments are able to run commands when the virtual environment is activated. Virtual
    environments which are not created by an attacker or which aren't activated before being used (ie
    ./venv/bin/python) are not affected.

    CVE-2024-12254:
    Starting in Python 3.12.0, the asyncio._SelectorSocketTransport.writelines()
     method would not pause writing and signal to the Protocol to drain
    the buffer to the wire once the write buffer reached the high-water
    mark. Because of this, Protocols would not periodically drain the write
     buffer potentially leading to memory exhaustion.





    This
     vulnerability likely impacts a small number of users, you must be using
     Python 3.12.0 or later, on macOS or Linux, using the asyncio module
    with protocols, and using .writelines() method which had new
    zero-copy-on-write behavior in Python 3.12.0 and later. If not all of
    these factors are true then your usage of Python is unaffected.

Tenable has extracted the preceding description block directly from the Tencent Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
number.");
