Network communication When an IFP proxy had been configured on Web Gateway, processing requests failed several times, as not only the requested URLs were submitted, which would have been compliant with the IFP protocol, but complete request headers. (1012953) The core process failed with term signal 11 due to a problem with a flag that had incorrectly not been reset after handling a long-running connections error. (1013944) Port 8443 was no longer available for listening to incoming requests because it was occupied by an internal Web Gateway service. (1016903) Web filtering When quota rules were synchronized in a Central Management cluster, the core process failed on one appliance with term signal 6. (965782) Real-time streaming data could not be processed due to a problem with the Helix proxy that had been enabled on Web Gateway for this purpose. (968670) Three new URL-related properties could not be saved and used in rules, as they worked only when embedded in error templates. (1003353) The dashboard did not show the update status of the McAfee Anti-Malware engine on the System Summary table. (1009924) The user interface was not accessible and an error message stated that the internal configurator could not be started, which was caused by a problem with an invalid list entry. (1011579) Error messages about the state of the Reporting.URL.Categories property were created, although the value of the URL.Categories property was already known and should have been used to determine the value of the former property. (1012372) Data for an update could not be downloaded from the web over a next-hop proxy when the Verify SSL Tunnel setting was enabled, as this setting triggered some requests that could not be sent over a next-hop proxy. (1014413) When the URL.SmartMatch property was used to find out whether entries in a list matched parts of requested URLs, a list entry beginning with a dash would match any URL. (1016043) After receiving an ICAP request without a host header on Web Gateway, an internal URL filtering error occurred when the URL.Categories property was processed. (1016815) The URL filtering module sent a query to a DNS server that included a port number, which caused the lookup to fail. (1017961) A request was blocked in SSL-secured communication when the certificate chain was erroneously taken to contain an expired certificate, as an intermediate certificate authority used a time format that could not be processed correctly. (1019470) Download of an Adobe Acrobat archive file was blocked because it was falsely suspected to be malware after scanning. (1023940) Miscellaneous When text was searched to process rules for Data Loss Prevention (DLP), words containing particular Russian letters were not supported due to an issue with character conversion. (985776) Entries in the PDStorage user map were not correctly removed when their lifetime was exceeded, nor when the PDStorage.Cleanup event was used in a rule. (1003320) The table for configuring static routes disappeared and connections were dissolved after 208 entries had been inserted. (1010222) 2
The core process failed with term signal 11 due to a file reading problem. (1010432) Wrong incident IDs were shown on the dashboard for successful and failed scheduled jobs. (1013435) When a scheduled job could not download a new version of a proxy.pac file due to a connection issue, the existing version of the file was overwritten with an empty file. (1015284) The explaining text for SNMP monitoring that is provided on Web Gateway did not mention a severity level 6, although an SNMP trap with this level was shown on the managing system. (1012051) After upgrading to a new version of Web Gateway, some alerts were incorrectly repeated on the dashboard many times. (1012254) The core process failed with term signal 11 due to an internal problem, which occurred when maps were written for rule tracing.
