Issues Resolved in Version 5.3.0.2

Resolved an issue where, if you created a custom workflow with a large 

number of pages, the time window in the top right portion of the page 

obscured the link to the final pages of the workflow. (141335)

Resolved an issue where, in some cases, FireSIGHT rule recommendations 

attempted to activate a preprocessor rule that was already active, causing 

system problems. (141439)

Resolved an issue where, in rare cases, if you added multiple passive 

interfaces to a security zone, then referenced the security zone in a 

managed device configuration, the configuration apply failed and the 

system experienced a disruption in detection. (141624, 141627)

Resolved an issue where, if one or more detection resources were 

unresponsive on a managed device, installing an update of the vulnerability 

database (VDB) caused system issues. (141757)

Improved efficiency and memory management of the disk manager. 

(141795)

Improved the stability of Snort when inspecting traffic transmitted via Real 

Time Streaming Protocol (RTSP). (141815)

Resolved an issue where completing a large number of access control 

policy applies caused the system to experience a memory issue and 

generate multiple 

High unmanaged disk usage

 health alerts. (141830)

Resolved an issue where, in some cases, revisions to the network address 

translation (NAT) policy caused system problems. (142003)

Resolved an issue where, in rare cases, Series 3 devices experienced 

delays during device shutdown. (142033)

Issues Resolved in Previous Updates

Because you can update your appliances from Version 5.3 to Version 5.3.0.2, this 

update also includes the changes from Version 5.3. Previously resolved issues are 

listed by version.

Version 5.3.0.1

Resolved an issue where, in rare cases, configuring an intrusion policy that 

contained local intrusion rules in a layer that was shared with another 

intrusion policy caused intrusion policy exports to fail. (132312)

Resolved an issue where, in rare cases, Snort stopped processing packets if 

any of your intrusion rules contained the Sensitive Data (sdf) rule 

classification. (132600)

Resolved an issue where, in rare cases, Snort drained system resources if 

you created and applied an access control policy with rules that specified an 

unusually large range of ports and contained other rule conditions that 

would cause the Defense Center to send them to the device in expanded 

form. (132998)
