Description William Lovaton 2013-04-22 10:07:10 EDT

After upgrading my gateway mail server from RHEL 6.3 to RHEL 6.4 SELinux is showing the following:

type=AVC msg=audit(1366639171.849:29610): avc:  denied  { execute } for  pid=25790 comm="amavisd" name="bash" dev=dm-0 ino=38 scontext=system_u:system_r:amavis_t:s0 tcontext=system_u:object_r:shell_exec_t:s0 tclass=file

It would seem it's not letting amavis to execute 7za.  The weird thing is that it was working fine in RHEL 6.3.  I'm going to create a local policy module to allow the access but I'd like to know your point of view regarding this AVC.

Thanks a lot.

Comment 1 Daniel Walsh 2013-04-22 10:46:02 EDT

We have this allowed in F19.

Might be an updated version of amavisd.

Miroslave we probably shold back port the other fixes in the te file.

Comment 2 William Lovaton 2013-04-22 10:52:27 EDT

Yep, you are right, EPEL updated Amavis from 2.6.4 to 2.8.0 and I applied those too after upgrading RHEL to 6.4.

Comment 3 Miroslav Grepl 2013-04-23 04:01:38 EDT

Yes, basically I want to back port

# seinfo -xtamavis_t
   TypeName antivirus_t
   Aliases
      amavis_t
      clamd_t
      freshclam_t
      clamscan_t

Comment 8 Miroslav Grepl 2013-08-06 04:03:16 EDT

I merged 

      amavis_t
      clamd_t
      freshclam_t
      clamscan_t

to antivirus_t.
