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 :

  - 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)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

The remote Redhat Enterprise Linux 7 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.
