According to the versions of the curl package installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :

  - It was found that libcurl did not safely parse FTP URLs     when using the CURLOPT_FTP_FILEMETHOD method. An     attacker, able to provide a specially crafted FTP URL     to an application using libcurl, could write a NULL     byte at an arbitrary location, resulting in a crash, or     an unspecified behavior.(CVE-2018-1000120)

  - A NULL pointer dereference flaw was found in the way     libcurl checks values returned by the openldap     ldap_get_attribute_ber() function. A malicious LDAP     server could use this flaw to crash a libcurl client     application via a specially crafted LDAP     reply.(CVE-2018-1000121)

  - A buffer over-read exists in curl 7.20.0 to and     including curl 7.58.0 in the RTSP+RTP handling code     that allows an attacker to cause a denial of service or     information leakage(CVE-2018-1000122)

  - curl version curl 7.20.0 to and including curl 7.59.0     contains a Buffer Over-read vulnerability in denial of     service that can result in curl can be tricked into     reading data beyond the end of a heap based buffer used     to store downloaded rtsp content.(CVE-2018-1000301)

  - curl version curl 7.20.0 to and including curl 7.59.0     contains a Buffer Over-read vulnerability in denial of     service that can result in curl can be tricked into     reading data beyond the end of a heap based buffer used     to store downloaded rtsp content.(CVE-2016-9586)

  - libcurl may read outside of a heap allocated buffer     when doing FTP. When libcurl connects to an FTP server     and successfully logs in (anonymous or not), it asks     the server for the current directory with the `PWD`     command. The server then responds with a 257 response     containing the path, inside double quotes. The returned     path name is then kept by libcurl for subsequent uses.
    Due to a flaw in the string parser for this directory     name, a directory name passed like this but without a     closing double quote would lead to libcurl not adding a     trailing NUL byte to the buffer holding the name. When     libcurl would then later access the string, it could     read beyond the allocated heap buffer and crash or     wrongly access data beyond the buffer, thinking it was     part of the path. A malicious server could abuse this     fact and effectively prevent libcurl-based clients to     work with it - the PWD command is always issued on new     FTP connections and the mistake has a high chance of     causing a segfault. The simple fact that this has issue     remained undiscovered for this long could suggest that     malformed PWD responses are rare in benign servers. We     are not aware of any exploit of this flaw. This bug was     introduced in commit     [415d2e7cb7](https://github.com/curl/curl/commit/415d2e     7cb7), March 2005. In libcurl version 7.56.0, the     parser always zero terminates the string but also     rejects it if not terminated properly with a final     double quote.i1/4^CVE-2017-1000254i1/4%0

  - The FTP wildcard function in curl and libcurl before     7.57.0 allows remote attackers to cause a denial of     service (out-of-bounds read and application crash) or     possibly have unspecified other impact via a string     that ends with an '[' character.The FTP wildcard     function in curl and libcurl before 7.57.0 allows     remote attackers to cause a denial of service     (out-of-bounds read and application crash) or possibly     have unspecified other impact via a string that ends     with an '[' character.i1/4^CVE-2017-8817i1/4%0

The remote Redhat Enterprise Linux 6 / 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2018:3558 advisory.

    The Apache HTTP Server is a powerful, efficient, and extensible web server. The httpd24 packages provide a     recent stable release of version 2.4 of the Apache HTTP Server, along with the mod_auth_kerb module.

    The following packages have been upgraded to a later upstream version: httpd24-httpd (2.4.34),     httpd24-curl (7.61.1). (BZ#1590833, BZ#1648928)

    Security Fix(es):

    * httpd: Improper handling of headers in mod_session can allow a remote user to modify session data for     CGI applications (CVE-2018-1283)

    * httpd: Out of bounds read in mod_cache_socache can allow a remote attacker to cause DoS (CVE-2018-1303)

    * httpd: mod_http2: Too much time allocated to workers, possibly leading to DoS (CVE-2018-1333)

    * httpd: DoS for HTTP/2 connections by continuous SETTINGS frames (CVE-2018-11763)

    * httpd: Out of bounds write in mod_authnz_ldap when using too small Accept-Language values     (CVE-2017-15710)

    * httpd: <FilesMatch> bypass with a trailing newline in the file name (CVE-2017-15715)

    * httpd: Out of bounds access after failure in reading the HTTP request (CVE-2018-1301)

    * httpd: Weak Digest auth nonce generation in mod_auth_digest (CVE-2018-1312)

    * curl: Multiple security issues were fixed in httpd24-curl (CVE-2016-5419, CVE-2016-5420, CVE-2016-5421,     CVE-2016-7141, CVE-2016-7167, CVE-2016-8615, CVE-2016-8616, CVE-2016-8617, CVE-2016-8618, CVE-2016-8619,     CVE-2016-8620, CVE-2016-8621, CVE-2016-8622, CVE-2016-8623, CVE-2016-8624, CVE-2016-8625, CVE-2016-9586,     CVE-2017-1000100, CVE-2017-1000101, CVE-2017-1000254, CVE-2017-1000257, CVE-2017-7407, CVE-2017-8816,     CVE-2017-8817, CVE-2018-1000007, CVE-2018-1000120, CVE-2018-1000121, CVE-2018-1000122, CVE-2018-1000301,     CVE-2018-14618)

    Bug Fix(es):

    * Previously, the Apache HTTP Server from the httpd24 Software Collection was unable to handle situations     when static content was repeatedly requested in a browser by refreshing the page. As a consequence, HTTP/2     connections timed out and httpd became unresponsive. This bug has been fixed, and HTTP/2 connections now     work as expected in the described scenario. (BZ#1518737)

    Enhancement(s):

    * This update adds the mod_md module to the httpd24 Software Collection. This module enables managing     domains across virtual hosts and certificate provisioning using the Automatic Certificate Management     Environment (ACME) protocol. The mod_md module is available only for Red Hat Enterprise Linux 7.
