Issues Resolved in Version 5.2.0.5

Version 5.2.0.4

Resolved an issue where, in some cases, NAT rule validation failed if you 

configured a static NAT rule with an original destination network that 

overlapped the translated source network on a dynamic NAT rule in the 

same NAT policy. (131490)

Resolved an issue where, after you selected Logarithmic as the Vertical 

Scale for the Intrusion Event dashboard widget, the system refreshed the 

widget and instead displayed the data using the default Linear Vertical Scale. 

(132203)

Improved the stability of host data queries to the eStreamer client. (132239, 

134244, 134295)

Improved the stability of connection event processing if your correlation 

policy contained a rule based on a connection event and specified a 

NETBIOS Name rule condition. (132562)

Resolved an issue where the eStreamer client omitted intrusion rule name 

metadata for intrusion events if you associated a Sourcefire-provided 

intrusion policy with an access control rule on a Defense Center running 

Version 5.2.0.2. (132667)

Improved system stability in cases where you applied an access control 

policy revision that changed the file inspection options in an access control 

rule. (132741)

Resolved an issue where setting the maximum transmission unit (MTU) of 

an inline set on a Series 2 or a virtual device to a value below 

1518

 caused a

Resolved a NTP time synchronization issue between managed devices and 
Defense Centers. (121909)

recommendations did not generate if an intrusion rule variable contained a 

network object. (125910)

Resolved an issue where, in some cases, the eStreamer client failed to 

deserialize network discovery user events and the system generated an 

error message. (126827)

Resolved an issue where, after updating an appliance running Version 5.1.x 

of the Sourcefire 3D System and Version 2.0.3 of the Sourcefire User Agent 

to Version 5.2 of the Sourcefire 3D System, the system generated an 

extraneous health alert. (127082, 127265, 127724)

Resolved an issue where, if the system logged the only intrusion event 

associated with a connection as

connection logged with the incorrect action of
