|CYV-14575||Fixed an issue where Linux processes were not visible from Process Management in the ESM Console.|
|CYV-14573||Fixed an issue where Traps retained irrelevant (unmapped) records inside both DLL Security and UASLR modules, which caused Traps to incorrectly report security events.|
|CYV-14560||Fixed an issue where Content Updates on the ESM Console did not display any indication that the policy is up-to-date when you Check Now for the latest update.|
|CYV-14559||Fixed an issue where Content Updates on the ESM Console did not automatically refresh when you Check Now for updates and the ESM Console identified a new content update was available.|

|CYV-14533||Fixed an issue where the ESM Console displayed a timed out status for a Tech Support File that had partially completed.

|CYV-14338||Fixed an issue in deployments with multiple ESM Servers and multiple NICs per ESM Server where the Traps agent did not received the full list of valid ESM Server addresses when the IP address for an ESM Server changed.|
|CYV-14159||Fixed an issue where the Traps EventReportsManager halted an action, such as sending reports, if it received a change to the reporting configuration before the action completed.|
Issues Addressed in Traps Endpoint Security Manager 4.2.1-h3
There are no issues addressed in the Traps Endpoint Security Manager 4.2.1-h3 release.
Issues Addressed in Traps Endpoint Security Manager 4.2.1-h2
The following table lists the issues that are addressed in the Traps Endpoint Security Manager 4.2.1-h2 release.
|Fixed a high memory consumption issue that was caused when Traps terminated a protected process.|
|Fixed an upgrade issue where after upgrading an ESM to 4.2.1, the Internal/External Address fields in Multi-ESM settings reverted to default values. Now, the ESM retains any configured Multi-ESM settings following an upgrade.|
Issues Addressed in Traps Endpoint Security Manager 4.2.1-h1
The following table lists the issues that are addressed in the Traps Endpoint Security Manager 4.2.1-h1 release.
|Fixed an issue with the Kernel Escalation Privilege exploit protection module which caused high CPU consumption on Linux endpoints.|
Issues Addressed in Traps Endpoint Security Manager 4.2.1
The following table lists the issues that are addressed in the Traps Endpoint Security Manager 4.2.1 release.
|Fixed an issue that occurred during an upgrade where the ESM Server loaded all records from the Protected Processes table into memory which caused high memory and CPU consumption.|
|Fixed an issue that caused the CyveraService process to consume up to 8GB of memory when loading the protected processes and resulted in high memory and CPU consumption at every agent heartbeat.|
|Fixed an issue with the Traps agent, where if you attempted to Send Support File, the agent would disconnect from the ESM Server and had to be manually restarted using Cytool.|
|Fixed an issue where the ESM Console reported multiple post detection events at each verdict recheck interval instead of a single post-detection event.|
|Fixed an issue with support exceptions delivered through content updates where the agent could not retrieve rules from the ESM Server when the rule name contained a backslash (\) in certain positions.|
|Fixed an issue where deleting security events from the ESM Console failed due to a missing mapping in the database.|
|Fixed an issue where if you cleared an administrative hash override from and the ESM Console could not connect to WildFire, the verdict did not reset to the previous verdict issued by Local Analysis.|
|Fixed an issue where the ESM Server upgrade was unsuccessful if the local user account assigned to manage the server contained spaces in the account name.|
|Fixed an issue where exporting Security Error Logs included reports for agent and ESM logs not related to security errors.|
|Fixed an issue where if you enabled log forwarding to an email, and performed a bulk operation from the ESM Console (such as deleting multiple rules simultaneously), the ESM logs the first operation but is unsuccessful reporting additional operations.|
|Fixed an issue on Windows endpoints where Traps agents caused slowness opening large excel files from the network due to the hash reporting process.|
|Fixed an issue where the ESM Console did not count agents in the Dashboard License Capacity chart due to missing data in the database.|
|Fixed an issue where the Traps local analysis service consumed all the CPU usage on an endpoint.|
|Fixed an issue where the ESM did not properly clone child process rules. With this fix, the ESM first matches parent rules containing lists (for example, blacklist or whitelist) and determines changes to the lists. The ESM then creates a single process exception rule to capture the change to the policy. For cloned rules that removed a process from a blacklist, the ESM creates a new rule which allows the removed process. For cloned rules that added a process to a blacklist, the ESM creates a new rule which blocks the added process.|
|Fixed an issue on Linux endpoints, where installation was unsuccessful when multiple OpenSSL Package Manager (RPM) packages were installed.|
|Fixed an issue where the ESM Console could not display details for some Post-Detection events.|
|Fixed an issue where the NUM-agents_per_version query in the Tech Support File included information about deleted (Historic) endpoints.|
|Fixed an upgrade issue where the ESM would receive multiple quarantine file notifications after you upgraded the Traps agent. This was due to a deleted registry key during the upgrade which caused the Traps service to process the quarantine event log from the beginning and retransmit all the logged events.|
|Fixed an issue where honeypot files used to identify ransomware were shown in legitimate apps that did not need to view the files. With this fix all honeypot files associated with the Anti-Ransomware Protection module are hidden to ensure legitimate apps do not interact with the files.|
|Fixed an issue where Traps Anti-Ransomware Protection module did not prevent suspicious activities by processes launched from known protected locations. With this fix, Palo Alto Networks can now distribute definitions for known protected locations with content updates.|
|Fixed an issue where you could not test log forwarding to an email containing a gmail.com email address.|
|Fixed an issue where after installing Traps on a new endpoint, Traps ignored an administrative override to block a file (and permitted the file to run) when the file was signed by a trusted signer.|
Issues Addressed in Traps Endpoint Security Manager 4.2.0
The following table lists the issues that are addressed in the Traps Endpoint Security Manager 4.2.0 release.
Fixed an issue where the ESM Console retained any command-line arguments specified for the child processes when you cloned a child process protection rule and remove the list of child processes.
Fixed an issue in the details view of a child process protection rule, where the Restricted List Module details are truncated.
Fixed an issue where the ESM Server failed to download files from the IIS virtual folder when the ESM Server was running on the same host as IIS (where the virtual folder is defined for forensic files).
Fixed an issue where if you accessed the ESM Console on the same server where IIS is running, the ESM Console was not displayed correctly.
Fixed an issue where if you defined an uninstall password from the ESM Console, the ESM Console ignored the definition and retained the default password of Password1.
Fixed an issue on the ESM Console Dashboard where the agent version extends beyond the width of the chart.
Fixed an issue where Traps evaluated the blacklisted processes before any restricted child processes. Now, Traps does not block child processes that were expressly allowed in the child process protection rules for a single source process.
Fixed an issue that occurred where if you cloned a default rule and then added additional components (processes), Traps failed to receive the changes to the default rule.
