The remote Alibaba Cloud Linux 3 host has packages installed that are affected by multiple vulnerabilities as referenced in the ALINUX3-SA-2024:0040 advisory.

    Package updates are available for Alibaba Cloud Linux 3 that fix the following vulnerabilities:

    CVE-2007-4559:
    Directory traversal vulnerability in the (1) extract and (2) extractall functions in the tarfile module in     Python allows user-assisted remote attackers to overwrite arbitrary files via a .. (dot dot) sequence in     filenames in a TAR archive, a related issue to CVE-2001-1267.

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

    CVE-2022-48564:
    read_ints in plistlib.py in Python through 3.9.1 is vulnerable to a potential DoS attack via CPU and RAM     exhaustion when processing malformed Apple Property List files in binary format.

    CVE-2023-27043:
    The email module of Python through 3.11.3 incorrectly parses e-mail addresses that contain a special     character. The wrong portion of an RFC2822 header is identified as the value of the addr-spec. In some     applications, an attacker can bypass a protection mechanism in which application access is granted only     after verifying receipt of e-mail to a specific domain (e.g., only @company.example.com addresses may be     used for signup). This occurs in email/_parseaddr.py in recent versions of Python.

    CVE-2023-40217:
    An issue was discovered in Python before 3.8.18, 3.9.x before 3.9.18, 3.10.x before 3.10.13, and 3.11.x     before 3.11.5. It primarily affects servers (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.)

Tenable has extracted the preceding description block directly from the Alibaba Cloud 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.

    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.

    We recommend that you upgrade your python3.7 packages.

    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.)


    For Debian 10 buster, these problems have been fixed in version     2.7.16-2+deb10u3.
