SNS 3.11.10 LTSB bug fixes
System
SNMP Agent
Support reference 78761
SNMP informRequest messages are now considered valid SNMP requests and no longer raise the blocking alarm “Invalid SNMP protocol" (snmp:388).
Support reference 82661
The correct value is now returned in the OID UCD-SNMP-MIB::memCached.0.
Disk monitoring
Support references 75125 - 75126 - 83541
An issue with alarms being wrongly raised over the disk status of firewalls has been fixed.
Initial configuration via USB key
Support reference 80866
In an initial configuration via USB key, when an additional .CSV configuration file was imported into the installation sequence, the command entered in the last line of the file was not executed. This issue has been fixed.
Support reference 81713
During the initial configuration via USB key, changes to the reference time zone specified in the additional configuration file in CSV format are now correctly applied.
IP address reputation and geolocation service
Support reference 81048
In some cases, the IP address reputation and geolocation service would unexpectedly shut down after competing access that occurs when a configuration is reloaded. Even when it was automatically restarted, service could still be disrupted. This issue has been fixed.
Intrusion prevention
SMB v2 protocol
Support reference 78216
An anomaly in the SMB protocol analysis engine would wrongly raise the "Invalid NBSS/SMB2 protocol" alarm (nb-cifs alarm:157), blocking legitimate SMBv2 traffic as a result. This issue has been fixed.
SIP
Support references 79839 - 79344
Anomalies in the SIP protocol analysis engine, which could cause the firewall to freeze, have been fixed.
