CVE-2011-0343: Oneidentity Syslog-NG

Medium severity, CVSS 6.9. EPSS: 0.4% chance of exploitation in the next 30 days.

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.

Affected products

• Oneidentity Syslog-NG: version 2.0 only; version 3.0 only; version 3.1 only; version 3.2 only
