Description of problem:
SELinux is preventing /usr/sbin/httpd from using the 'execstack' accesses on a process.

*****  Plugin catchall_boolean (89.3 confidence) suggests   ******************

If vous souhaitez autoriser les scripts et modules httpd execmem/execstack
Then vous devez en informer SELinux en activant le booléen « httpd_execmem ».
Vous pouvez lire la page de manuel « httpd_selinux » pour plus de détails.
Do
setsebool -P httpd_execmem 1

*****  Plugin catchall (11.6 confidence) suggests   **************************

If vous pensez que httpd devrait être autorisé à accéder execstack sur les processus étiquetés httpd_t par défaut.
Then vous devriez rapporter ceci en tant qu'anomalie.
Vous pouvez générer un module de stratégie local pour autoriser cet accès.
Do
autoriser cet accès pour le moment en exécutant :
# grep httpd /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

Comment 1 Simon Sekidde 2013-12-30 14:59:54 UTC
Nicholas, 

To allow httpd scripts and modules execmem/execstack turn on the boolean 

# setsebool -P httpd_execmem 1
