CVE-2015-3243
Description
From CVE.org
rsyslog uses weak permissions for generating log files, which allows local users to obtain sensitive information by reading files in /var/log/cron.
Statement
This issue affects the versions of rsyslog as shipped with Red Hat Enterprise Linux 7. Red Hat Product Security has rated this issue as having Low security impact. A future update may address this issue. For additional information, refer to the Issue Severity Classification: https://access.redhat.com/security/updates/classification/. Additionally a workaround is available (https://bugzilla.redhat.com/show_bug.cgi?id=1232826#c3).
Mitigation
Please add:
create 0600 root root
to the /etc/logrotate.d/syslog file, this will ensure the file is created with permissions when logrotate runs. It is also recommended that users manually set the permissions on existing or newly installed log files in order to prevent access by untrusted users.
