The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2020:1462 advisory.

    Python is an interpreted, interactive, object-oriented programming language, which includes modules,     classes, exceptions, very high level dynamic data types and dynamic typing. Python supports interfaces to     many system calls and libraries, as well as to various windowing systems.

    Security Fix(es):

    * python: Missing salt initialization in _elementtree.c module (CVE-2018-14647)

    * python: CRLF injection via the query part of the url passed to urlopen() (CVE-2019-9740)

    * python: CRLF injection via the path part of the url passed to urlopen() (CVE-2019-9947)

    * python: Undocumented local_file protocol allows remote attackers to bypass protection mechanisms     (CVE-2019-9948)

    For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and     other related information, refer to the CVE page(s) listed in the References section.

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

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

  - library/glob.html in the Python 2 and 3 documentation     before 2016 has potentially misleading information     about whether sorting occurs, as demonstrated by     irreproducible cancer-research results. NOTE: the     effects of this documentation cross application     domains, and thus it is likely that security-relevant     code elsewhere is affected. This issue is not a Python     implementation bug, and there are no reports that NMR     researchers were specifically relying on     library/glob.html. In other words, because the older     documentation stated 'finds all the pathnames matching     a specified pattern according to the rules used by the     Unix shell,' one might have incorrectly inferred that     the sorting that occurs in a Unix shell also occurred     for glob.glob. There is a workaround in newer versions     of Willoughby nmr-data_compilation-p2.py and     nmr-data_compilation-p3.py, which call sort()     directly.(CVE-2019-17514)

  - The documentation XML-RPC server in Python through     2.7.16, 3.x through 3.6.9, and 3.7.x through 3.7.4 has     XSS via the server_title field. This occurs in     Lib/DocXMLRPCServer.py in Python 2.x, and in     Lib/xmlrpc/server.py in Python 3.x. If set_server_title     is called with untrusted input, arbitrary JavaScript     can be delivered to clients that visit the http URL for     this server.(CVE-2019-16935)

  - An issue was discovered in urllib2 in Python 2.x     through 2.7.16 and urllib in Python 3.x through 3.7.3.
    CRLF injection is possible if the attacker controls a     url parameter, as demonstrated by the first argument to     urllib.request.urlopen with \r\n (specifically in the     query string after a ? character) followed by an HTTP     header or a Redis command.(CVE-2019-9740)

  - An issue was discovered in Python through 2.7.16, 3.x     through 3.5.7, 3.6.x through 3.6.9, and 3.7.x through     3.7.4. The email module wrongly parses email addresses     that contain multiple @ characters. An application that     uses the email module and implements some kind of     checks on the From/To headers of a message could be     tricked into accepting an email address that should be     denied. An attack may be the same as in CVE-2019-11340     however, this CVE applies to Python more     generally.(CVE-2019-16056)

  - http.cookiejar.DefaultPolicy.domain_return_ok in     Lib/http/cookiejar.py in Python before 3.7.3 does not     correctly validate the domain: it can be tricked into     sending existing cookies to the wrong server. An     attacker may abuse this flaw by using a server with a     hostname that has another valid hostname as a suffix     (e.g., pythonicexample.com to steal cookies for     example.com). When a program uses     http.cookiejar.DefaultPolicy and tries to do an HTTP     connection to an attacker-controlled server, existing     cookies can be leaked to the attacker. This affects 2.x     through 2.7.16, 3.x before 3.4.10, 3.5.x before 3.5.7,     3.6.x before 3.6.9, and 3.7.x before     3.7.3.(CVE-2018-20852)

The version of AOS installed on the remote host is prior to 5.11.2. It is, therefore, affected by multiple vulnerabilities as referenced in the NXSA-AOS-5.11.2 advisory.

  - Gnome Pango 1.42 and later is affected by: Buffer Overflow. The impact is: The heap based buffer overflow     can be used to get code execution. The component is: function name: pango_log2vis_get_embedding_levels,     assignment of nchars and the loop condition. The attack vector is: Bug can be used when application pass     invalid utf-8 strings to functions like pango_itemize. (CVE-2019-1010238)

  - curl before version 7.61.1 is vulnerable to a buffer overrun in the NTLM authentication code. The internal     function Curl_ntlm_core_mk_nt_hash multiplies the length of the password by two (SUM) to figure out how     large temporary storage area to allocate from the heap. The length value is then subsequently used to     iterate over the password and generate output into the allocated storage buffer. On systems with a 32 bit     size_t, the math to calculate SUM triggers an integer overflow when the password length exceeds 2GB (2^31     bytes). This integer overflow usually causes a very small buffer to actually get allocated instead of the     intended very huge one, making the use of that buffer end up in a heap buffer overflow. (This bug is     almost identical to CVE-2017-8816.) (CVE-2018-14618)

  - An issue was discovered in XListExtensions in ListExt.c in libX11 through 1.6.5. A malicious server can     send a reply in which the first string overflows, causing a variable to be set to NULL that will be freed     later on, leading to DoS (segmentation fault). (CVE-2018-14598)

  - An issue was discovered in libX11 through 1.6.5. The function XListExtensions in ListExt.c is vulnerable     to an off-by-one error caused by malicious server responses, leading to DoS or possibly unspecified other     impact. (CVE-2018-14599)

  - An issue was discovered in libX11 through 1.6.5. The function XListExtensions in ListExt.c interprets a     variable as signed instead of unsigned, resulting in an out-of-bounds write (of up to 128 bytes), leading     to DoS or remote code execution. (CVE-2018-14600)
