EulerOS 2.0 SP2 : tomcat (EulerOS-SA-2017-1082)

high Nessus Plugin ID 99948

Synopsis

The remote EulerOS host is missing multiple security updates.

Description

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.

Solution

Update the affected tomcat packages.
