Known Affected Versions:
12.1.0, 12.1.0 HF1, 12.1.0 HF2, 12.1.1, 12.1.1 HF1, 12.1.1 HF2

Fixed In:
13.0.0, 12.1.2

Opened: Oct 12, 2016
Severity: 3-Major


Whenever a DoS Network logging profile is assigned or removed from a Virtual Server, it could cause random TMM crash.


Traffic disrupted while tmm restarts.


The problem happens only with runtime config change. Any logging profile config settings which was configured already and which gets loaded on TMM startup does not have this problem. Since this problem is a one time event on config change, TMM restart will pickup the config change and will work without any problem after the one time crash and TMM restart.



Fix Information

Invalid memory reference after free resulted in crash, which is fixed.
