  - A carry propagating error exists in the x86_64     Montgomery squaring implementation that may cause the     BN_mod_exp() function to produce incorrect results. An     unauthenticated, remote attacker with sufficient     resources can exploit this to obtain sensitive     information regarding private keys. Note that this issue     is very similar to CVE-2015-3193. Moreover, the attacker     would additionally need online access to an unpatched     system using the target private key in a scenario with     persistent DH parameters and a private key that is     shared between multiple clients. For example, this can     occur by default in OpenSSL DHE based SSL/TLS cipher     suites. (CVE-2017-3732)

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 tomcat packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  - It was discovered that the code that parsed the HTTP     request line permitted invalid characters. This could     be exploited, in conjunction with a proxy that also     permitted the invalid characters but with a different     interpretation, to inject data into the HTTP response.
    By manipulating the HTTP response the attacker could     poison a web-cache, perform an XSS attack, or obtain     sensitive information from requests other then their     own. (CVE-2016-6816)

  - A bug was discovered in the error handling of the send     file code for the NIO HTTP connector. This led to the     current Processor object being added to the Processor     cache multiple times allowing information leakage     between requests including, and not limited to, session     ID and the response body. (CVE-2016-8745)

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 version of Tomcat installed on the remote host is prior to 9.0.0.M13. It is, therefore, affected by multiple vulnerabilities as referenced in the fixed_in_apache_tomcat_9.0.0.m13_security-9 advisory.

  - Remote code execution is possible with Apache Tomcat before 6.0.48, 7.x before 7.0.73, 8.x before 8.0.39,     8.5.x before 8.5.7, and 9.x before 9.0.0.M12 if JmxRemoteLifecycleListener is used and an attacker can     reach JMX ports. The issue exists because this listener wasn't updated for consistency with the     CVE-2016-3427 Oracle patch that affected credential types. (CVE-2016-8735)

  - The HTTP/2 header parser in Apache Tomcat 9.0.0.M1 to 9.0.0.M11 and 8.5.0 to 8.5.6 entered an infinite     loop if a header was received that was larger than the available buffer. This made a denial of service     attack possible. (CVE-2016-6817)

  - The code in Apache Tomcat 9.0.0.M1 to 9.0.0.M11, 8.5.0 to 8.5.6, 8.0.0.RC1 to 8.0.38, 7.0.0 to 7.0.72, and     6.0.0 to 6.0.47 that parsed the HTTP request line permitted invalid characters. This could be exploited,     in conjunction with a proxy that also permitted the invalid characters but with a different     interpretation, to inject data into the HTTP response. By manipulating the HTTP response the attacker     could poison a web-cache, perform an XSS attack and/or obtain sensitive information from requests other     then their own. (CVE-2016-6816)

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

This updates includes a rebase from tomcat 8.0.38 up to 8.0.39 which resolves multiple CVEs :
