Description of problem:
SELinux is preventing hl2_linux from using the 'execheap' accesses on a process.

*****  Plugin allow_execheap (53.1 confidence) suggests   ********************

If no cree que hl2_linux debería necesitar mapear memoria del heap que sea a la vez escribible y ejecutable.
Then necesita informar de un error. Éste es un acceso potencialmente peligroso.
Do
póngase en contacto con su administrador de seguridad e informe de este problema.

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

If quiere allow selinuxuser to execheap
Then debe informar a SELinux de ésto activando el booleano 'selinuxuser_execheap'.

Do
setsebool -P selinuxuser_execheap 1

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

If cree que de manera predeterminada, hl2_linux debería permitir acceso execheap sobre procesos etiquetados como unconfined_t.
Then debería reportar esto como un error.
Puede generar un módulo de política local para permitir este acceso.
Do
allow this access for now by executing:
# ausearch -c 'hl2_linux' --raw | audit2allow -M my-hl2linux
# semodule -X 300 -i my-hl2linux.pp

Comment 1 Fedora End Of Life 2018-05-03 04:30:24 EDT
This message is a reminder that Fedora 26 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 26. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as EOL if it remains open with a Fedora  'version'
of '26'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version.

Thank you for reporting this issue and we are sorry that we were not
able to fix it before Fedora 26 is end of life. If you would still like
to see this bug fixed and are able to reproduce it against a later version
of Fedora, you are encouraged  change the 'version' to a later Fedora
version prior this bug is closed as described in the policy above.

Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.

Note You need to log in before you can comment on or make changes to this bug.
