CVE-2021-34598

Name of the Vulnerable Software and Affected Versions: Phoenix Contact FL MGUARD 1102 and 1105 versions 1.4.0 through 1.5.0

Description: The remote logging functionality is impaired due to the lack of memory release for data structures from syslog-ng when remote logging is active.

Recommendations: For versions 1.4.0, 1.4.1, and 1.5.0, consider disabling the remote logging functionality until a patch is available to prevent memory issues. Restrict access to the syslog-ng data structures to minimize the risk of exploitation. Avoid using the remote logging feature in the affected versions until the issue is resolved.
