Description David Mulford 2017-08-23 17:51:20 EDT

SELinux is denying tomcat from connecting to Microsoft SQL Server on port 1433, with the following AVC denial in /var/log/audit.log

type=AVC msg=audit(1503434074.102:50305): avc:  denied  { name_connect } for  pid=4488 comm="java" dest=1433 scontext=system_u:system_r:tomcat_t:s0 tcontext=system_u:object_r:mssql_port_t:s0 tclass=tcp_socket

This worked without issue in previous versions of the targeted policy.


Version-Release number of selected component (if applicable):
  - selinux-policy-targeted-3.13.1-166.el7.noarch
  - RHEL 7.4

How reproducible:
Always

Steps to Reproduce:
1. Create a new RHEL 7.4 machine
2. yum install tomcat; systemctl start tomcat.service
3. Install a tomcat application that will connect to an existing MS SQL server.

Actual results:
AVC denial

Expected results:
A successful connection, like previous versions of the policy.

Hello,

This bug report indicates that this issue is resolved in version 3.13.1-174.el7 but the latest version I see available is 3.13.1-166.el7_4.4.

Is there an ETA on the release of the fixed version?

Thank you,

Justin
