The remote Redhat Enterprise Linux 6 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - mod_auth_mellon: open redirect in logout url when using URLs with backslashes (CVE-2019-3877)

  - The am_read_post_data function in mod_auth_mellon before 0.11.1 does not check if the ap_get_client_block     function returns an error, which allows remote attackers to cause a denial of service (segmentation fault     and process crash) via a crafted POST data. (CVE-2016-2145)

  - The am_read_post_data function in mod_auth_mellon before 0.11.1 does not limit the amount of data read,     which allows remote attackers to cause a denial of service (worker process crash, web server deadlock, or     memory consumption) via a large amount of POST data. (CVE-2016-2146)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

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

  - The am_read_post_data function in mod_auth_mellon     before 0.11.1 does not check if the ap_get_client_block     function returns an error, which allows remote     attackers to cause a denial of service (segmentation     fault and process crash) via a crafted POST     data.(CVE-2016-2145)

  - The am_read_post_data function in mod_auth_mellon     before 0.11.1 does not limit the amount of data read,     which allows remote attackers to cause a denial of     service (worker process crash, web server deadlock, or     memory consumption) via a large amount of POST     data.(CVE-2016-2146)

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

  - mod_auth_mellon before 0.13.1 is vulnerable to a     Cross-Site Session Transfer attack, where a user with     access to one web site running on a server can copy     their session cookie to a different web site on the     same server to get access to that site.(CVE-2017-6807)

  - The am_read_post_data function in mod_auth_mellon     before 0.11.1 does not check if the ap_get_client_block     function returns an error, which allows remote     attackers to cause a denial of service (segmentation     fault and process crash) via a crafted POST     data.(CVE-2016-2145)

  - The am_read_post_data function in mod_auth_mellon     before 0.11.1 does not limit the amount of data read,     which allows remote attackers to cause a denial of     service (worker process crash, web server deadlock, or     memory consumption) via a large amount of POST     data.(CVE-2016-2146)
