Description Retlaw Dlawso 2010-02-16 13:42:03 UTC
Summary:

SELinux is preventing /usr/bin/perl "write" access on
/etc/logwatch/scripts/services.

Detailed Description:

SELinux denied access requested by perl. It is not expected that this access is
required by perl and this access may signal an intrusion attempt. It is also
possible that the specific version or configuration of the application is
causing it to require additional access.

Allowing Access:

You can generate a local policy module to allow this access - see FAQ
(http://docs.fedoraproject.org/selinux-faq-fc5/#id2961385) Please file a bug
report.

audit2allow suggests:

#============= logwatch_t ==============
#!!!! The source type 'logwatch_t' can write to a 'dir' of the following types:
# var_lock_t, tmp_t, logwatch_cache_t, logwatch_tmp_t

allow logwatch_t etc_t:dir write;
