大家好，
我刚刚重装的centos7(CentOS-7.0-1406-x86_64-DVD.iso)
用yum update之后的版本是：
Linux localhost.localdomain 3.10.0-327.3.1.el7.x86_64 #1 SMP Wed Dec 9 14:09:15 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux
在yum update过程中,SELinux有几个Alert，然后光驱就弹出了. 不知道是不是被攻击？该怎么办？谢谢
Alert 1--
SELinux is preventing /usr/libexec/abrt-handle-event from open access on the file .
***** Plugin catchall (100. confidence) suggests **************************
If you believe that abrt-handle-event should be allowed open access on the file 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 abrt-handle-eve /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
