Scientific Linux Security Update : tomcat on SL7.x (noarch)

Medium Nessus Plugin ID 104269

Synopsis

The remote Scientific Linux host is missing one or more security updates.

Description

Security Fix(es) :

- A vulnerability was discovered in Tomcat's handling of pipelined requests when 'Sendfile' was used. If sendfile processing completed quickly, it was possible for the Processor to be added to the processor cache twice. This could lead to invalid responses or information disclosure. (CVE-2017-5647)

- Two vulnerabilities were discovered in Tomcat where if a servlet context was configured with readonly=false and HTTP PUT requests were allowed, an attacker could upload a JSP file to that context and achieve code execution.
(CVE-2017-12615, CVE-2017-12617)

- A vulnerability was discovered in Tomcat where the CORS Filter did not send a 'Vary: Origin' HTTP header. This potentially allowed sensitive data to be leaked to other visitors through both client-side and server-side caches. (CVE-2017-7674)

Solution

Update the affected packages.
