According to the versions of the python2 packages installed, the EulerOS Virtualization 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)

  - An issue was discovered in compare_digest in Lib/hmac.py in Python through 3.9.1. Constant-time-defeating     optimisations were possible in the accumulator variable in hmac.compare_digest. (CVE-2022-48566)

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.) (CVE-2023-40217)

  - 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-2023-27043)

The remote Debian 10 host has packages installed that are affected by multiple vulnerabilities as referenced in the dla-3614 advisory.

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

  - 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-2022-48564)

  - 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)

  - An issue was discovered in compare_digest in Lib/hmac.py in Python through 3.9.1. Constant-time-defeating     optimisations were possible in the accumulator variable in hmac.compare_digest. (CVE-2022-48566)

  - 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.) (CVE-2023-40217)

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

The remote SUSE Linux SLED12 / SLED_SAP12 / SLES12 / SLES_SAP12 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2023:4001-1 advisory.

  - 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)

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

  - The package python/cpython from 0 and before 3.6.13, from 3.7.0 and before 3.7.10, from 3.8.0 and before     3.8.8, from 3.9.0 and before 3.9.2 are vulnerable to Web Cache Poisoning via urllib.parse.parse_qsl and     urllib.parse.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-2021-23336)

  - A flaw was found in Python, specifically within the urllib.parse module. This 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. This flaw affects Python versions prior to 3.10.0b1,     3.9.5, 3.8.11, 3.7.11 and 3.6.14. (CVE-2022-0391)

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

  - An issue was discovered in compare_digest in Lib/hmac.py in Python through 3.9.1. Constant-time-defeating     optimisations were possible in the accumulator variable in hmac.compare_digest. (CVE-2022-48566)

  - An issue in the urllib.parse component of Python before 3.11.4 allows attackers to bypass blocklisting     methods by supplying a URL that starts with blank characters. (CVE-2023-24329)

  - 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.

The remote Ubuntu 16.04 ESM / 18.04 ESM host has packages installed that are affected by a vulnerability as referenced in the USN-6354-1 advisory.

    It was discovered that Python did not properly handle XML entity declarations in plist files. An attacker     could possibly use this vulnerability to perform an XML External Entity (XXE) injection, resulting in a     denial of service or information disclosure.

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