Descriptions

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.

Balabit syslog-ng v2.0, v3.0, v3.1, v3.2 OSE y PE, cuando se ejecutan en FreeBSD o HP-UX, no realiza adecuadamente las operaciones de conversión, esto provoca que syslog-ng emplee un valor por defecto de -1 para crear archivos de registro (log) con permisos no seguros (07777), lo que permite a usuarios locales leer y escribir en estos archivos de registro.
