遠端 Debian 10 主機上安裝的多個套件受到 dla-3614 公告中提及的多個弱點影響。

  - 在 Python 3.9 及更低版本中，透過 heapq 中的 heappushpop 存在釋放後使用弱點。(CVE-2022-48560)

  - 在 Python 3.9.1 及更低版本中，plistlib.py 的 read_ints 在處理二進位格式的格式錯誤 Apple Property List 檔案時，容易因 CPU 和 RAM 耗盡而受到潛在的 DoS 攻擊。(CVE-2022-48564)

  - 在 Python 3.9.1 及更低版本中發現 XML 外部實體 (XXE) 問題。plistlib 模組不再接受 XML plist 檔案中的實體宣告，以避免 XML 弱點。(CVE-2022-48565)

  - 在 Python 3.9.1 及更低版本的 Lib/hmac.py 之 compare_digest 中發現一個問題。在 hmac.compare_digest 的 accumulator 變數中可能進行常數時間失敗最佳化。(CVE-2022-48566)

  - 在 Python 3.8.18 之前的版本，3.9.18 之前的 3.9.x 版、3.10.13 之前的 3.10.x 版、3.11.5 之前的 3.11.x 版中發現一個問題。該弱點主要影響使用 TLS 用戶端驗證的伺服器 (例如 HTTP 伺服器)。如果建立了 TLS 伺服器端通訊端，將資料接收到通訊端緩衝區，然後快速關閉，則有一個短暫的視窗，SSLSocket 執行個體會將通訊端偵測為「未連線」，且不會發起交握，但攻擊者仍可從通訊端緩衝區讀取緩衝的資料。如果伺服器端 TLS 對等端預期收到用戶端憑證驗證，則此資料將不會經過驗證，且無法與有效的 TLS 資料流資料區別開來。資料大小限制為緩衝區可容納的數量。(TLS 連線無法直接用於資料洩漏，因為有弱點的程式碼路徑要求在 SSLSocket 初始化時關閉連線。) (CVE-2023-40217)

The remote Debian 10 host has packages installed that are affected by multiple vulnerabilities as referenced in the dla-3575 advisory.

    -------------------------------------------------------------------------     Debian LTS Advisory DLA-3575-1                debian-lts@lists.debian.org     https://www.debian.org/lts/security/                        Helmut Grohne     September 20, 2023                            https://wiki.debian.org/LTS
    -------------------------------------------------------------------------

    Package        : python2.7     Version        : 2.7.16-2+deb10u3     CVE ID         : CVE-2021-23336 CVE-2022-0391 CVE-2022-48560 CVE-2022-48565                      CVE-2022-48566 CVE-2023-24329 CVE-2023-40217

    This update fixes multiple vulnerabilities concerning the urlparse module as     well as vulnerabilities concerning the heapq, hmac, plistlib and ssl modules.

    CVE-2021-23336

        Python was vulnerable to Web Cache Poisoning via urlparse.parse_qsl and         urlparse.parse_qs by using a vector called parameter cloaking. When the         attacker can separate query parameters using a semicolon (;), they can         cause a difference in the interpretation of the request between the proxy         (running with default configuration) and the server. This can result in         malicious requests being cached as completely safe ones, as the proxy would         usually not see the semicolon as a separator, and therefore would not         include it in a cache key of an unkeyed parameter.

    CVE-2022-0391

        The urlparse module helps break Uniform Resource Locator (URL) strings into         components. The issue involves how the urlparse method does not sanitize         input and allows characters like '\r' and '\n' in the URL path.  This flaw         allows an attacker to input a crafted URL, leading to injection attacks.

    CVE-2022-48560

        A use-after-free exists in Python via heappushpop in heapq.

    CVE-2022-48565

        An XML External Entity (XXE) issue was discovered in Python.  The plistlib         module no longer accepts entity declarations in XML plist files to avoid         XML vulnerabilities.

    CVE-2022-48566

        An issue was discovered in compare_digest in Lib/hmac.py in Python.
        Constant-time-defeating optimisations were possible in the accumulator         variable in hmac.compare_digest.

    CVE-2023-24329

        An issue in the urlparse component of Python allows attackers to bypass         blocklisting methods by supplying a URL that starts with blank characters.

    CVE-2023-40217

        The issue primarily affects servers written in Python (such as HTTP         servers) that use TLS client authentication. If a TLS server-side socket is         created, receives data into the socket buffer, and then is closed quickly,         there is a brief window where the SSLSocket instance will detect the socket         as not connected and won't initiate a handshake, but buffered data will         still be readable from the socket buffer.  This data will not be         authenticated if the server-side TLS peer is expecting client certificate         authentication, and is indistinguishable from valid TLS stream data. Data         is limited in size to the amount that will fit in the buffer. (The TLS         connection cannot directly be used for data exfiltration because the         vulnerable code path requires that the connection be closed on         initialization of the SSLSocket.)

    Several vulnerabilities were discovered in Python 3.7.

    CVE-2022-48560

        A use-after-free problem was found in the heappushpop function in         the heapq module.

    CVE-2022-48564

        A potential denial-of-service vulnerability was discovered in the         read_ints function used when processing certain malformed Apple         Property List files in binary format.

    CVE-2022-48565

        An XML External Entity (XXE) issue was discovered.  In order to         avoid possible vulnerabilities, the plistlib module no longer         accepts entity declarations in XML plist files.

    CVE-2022-48566

        Possible constant-time-defeating compiler optimisations were         discovered in the accumulator variable in hmac.compare_digest.

    CVE-2023-40217

        It was discovered that it might be possible to bypass some of the         protections implemented by the TLS handshake in the ssl.SSLSocket         class.  For example, unauthenticated data might be read by a program         expecting data authenticated by client certificates.

    For Debian 10 buster, these problems have been fixed in version     3.7.3-2+deb10u6.

According to the versions of the python packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  - A use-after-free exists in Python through 3.9 via heappushpop in heapq. (CVE-2022-48560)

  - An XML External Entity (XXE) issue was discovered in Python through 3.9.1. The plistlib module no longer     accepts entity declarations in XML plist files to avoid XML vulnerabilities. (CVE-2022-48565)
