NVD Description

Note: Versions mentioned in the description apply only to the upstream syslog-ng package and not the syslog-ng package as distributed by Echo. See How to fix? for Echo:latest relevant fixed versions and status.

Balabit syslog-ng 2.0, 3.0, 3.1, 3.2 OSE and PE, when running on FreeBSD or HP-UX, does not properly perform cast operations, which causes syslog-ng to use a default value of -1 to create log files with insecure permissions (07777), which allows local users to read and write to these log files.
