SELinux is preventing /opt/Comcast Universal Caller ID/bin/Comcast Universal Caller ID from using the 'execstack' accesses on a process.

*****  Plugin allow_execstack (53.1 confidence) suggests  ********************

If you believe that 
None
should not require execstack
Then you should clear the execstack flag and see if /opt/Comcast Universal Caller ID/bin/Comcast Universal Caller ID works correctly.
Report this as a bug on None.
You can clear the exestack flag by executing:
Do
execstack -c None

*****  Plugin catchall_boolean (42.6 confidence) suggests  *******************

If you want to allow unconfined executables to make their stack executable.  This should never, ever be necessary. Probably indicates a badly coded executable, but could indicate an attack. This executable should be reported in bugzilla
Then you must tell SELinux about this by enabling the 'allow_execstack' boolean.
Do
setsebool -P allow_execstack 1

*****  Plugin catchall (5.76 confidence) suggests  ***************************

If you believe that Comcast Universal Caller ID should be allowed execstack access on processes labeled unconfined_t by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# grep 436F6D6361737420556E6976657273 /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
