The remote Rocky Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RLSA-2020:1605 advisory.

  - The Requests package before 2.20.0 for Python sends an HTTP Authorization header to an http URI upon     receiving a same-hostname https-to-http redirect, which makes it easier for remote attackers to discover     credentials by sniffing the network. (CVE-2018-18074)

  - urllib3 before version 1.23 does not remove the Authorization HTTP header when following a cross-origin     redirect (i.e., a redirect that differs in host, port, or scheme). This can allow for credentials in the     Authorization header to be exposed to unintended hosts or transmitted in cleartext. (CVE-2018-20060)

  - 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)

  - In the urllib3 library through 1.24.1 for Python, CRLF injection is possible if the attacker controls the     request parameter. (CVE-2019-11236)

  - The urllib3 library before 1.24.2 for Python mishandles certain cases where the desired set of CA     certificates is different from the OS store of CA certificates, which results in SSL connections     succeeding in situations where a verification failure is the correct outcome. This is related to use of     the ssl_context, ca_certs, or ca_certs_dir argument. (CVE-2019-11324)

  - 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)

  - 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)

According to the versions of the python-urllib3 package installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  - In the urllib3 library through 1.24.1 for Python, CRLF     injection is possible if the attacker controls the     request parameter.(CVE-2019-11236)

  - 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)

  - urllib3 before version 1.23 does not remove the     Authorization HTTP header when following a cross-origin     redirect (i.e., a redirect that differs in host, port,     or scheme). This can allow for credentials in the     Authorization header to be exposed to unintended hosts     or transmitted in cleartext.(CVE-2018-20060)

The version of AOS installed on the remote host is prior to 5.16. It is, therefore, affected by multiple vulnerabilities as referenced in the NXSA-AOS-5.16 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)

The version of AOS installed on the remote host is prior to 5.16.1.3. It is, therefore, affected by multiple vulnerabilities as referenced in the NXSA-AOS-5.16.1.3 advisory.

  - When using the Apache JServ Protocol (AJP), care must be taken when trusting incoming connections to     Apache Tomcat. Tomcat treats AJP connections as having higher trust than, for example, a similar HTTP     connection. If such connections are available to an attacker, they can be exploited in ways that may be     surprising. In Apache Tomcat 9.0.0.M1 to 9.0.0.30, 8.5.0 to 8.5.50 and 7.0.0 to 7.0.99, Tomcat shipped     with an AJP Connector enabled by default that listened on all configured IP addresses. It was expected     (and recommended in the security guide) that this Connector would be disabled if not required. This     vulnerability report identified a mechanism that allowed: - returning arbitrary files from anywhere in the     web application - processing any file in the web application as a JSP Further, if the web application     allowed file upload and stored those files within the web application (or the attacker was able to control     the content of the web application by some other means) then this, along with the ability to process a     file as a JSP, made remote code execution possible. It is important to note that mitigation is only     required if an AJP port is accessible to untrusted users. Users wishing to take a defence-in-depth     approach and block the vector that permits returning arbitrary files and execution as JSP may upgrade to     Apache Tomcat 9.0.31, 8.5.51 or 7.0.100 or later. A number of changes were made to the default AJP     Connector configuration in 9.0.31 to harden the default configuration. It is likely that users upgrading     to 9.0.31, 8.5.51 or 7.0.100 or later will need to make small changes to their configurations.
    (CVE-2020-1938)

  - rtl_p2p_noa_ie in drivers/net/wireless/realtek/rtlwifi/ps.c in the Linux kernel through 5.3.6 lacks a     certain upper-bound check, leading to a buffer overflow. (CVE-2019-17666)

  - The Linux kernel before 5.1-rc5 allows page->_refcount reference count overflow, with resultant use-after-     free issues, if about 140 GiB of RAM exists. This is related to fs/fuse/dev.c, fs/pipe.c, fs/splice.c,     include/linux/mm.h, include/linux/pipe_fs_i.h, kernel/trace/trace.c, mm/gup.c, and mm/hugetlb.c. It can     occur with FUSE requests. (CVE-2019-11487)

  - A flaw was found in the fix for CVE-2019-11135, in the Linux upstream kernel versions before 5.5 where,     the way Intel CPUs handle speculative execution of instructions when a TSX Asynchronous Abort (TAA) error     occurs. When a guest is running on a host CPU affected by the TAA flaw (TAA_NO=0), but is not affected by     the MDS issue (MDS_NO=1), the guest was to clear the affected buffers by using a VERW instruction     mechanism. But when the MDS_NO=1 bit was exported to the guests, the guests did not use the VERW mechanism     to clear the affected buffers. This issue affects guests running on Cascade Lake CPUs and requires that     host has 'TSX' enabled. Confidentiality of data is the highest threat associated with this vulnerability.
