Release Notes: This release adds many new features and fixes, including file capture and storage, file type identification, and updates to SMTP, POP, and IMAP.
Release Notes: This release fixed an issue with the SMTP preprocessor and the ignore_tls_data configuration correctly stopping inspection after an SMTP session is encrypted. All rule evaluation (as opposed to just rules with fast patterns) is now disabled for packets on a previously blocked session. The perfmon preprocessor now writes stats as soon as both the time and packet count criteria are met. The same restrictions are enforced on relative PCRE for HTTP buffers from shared library rules as already existed with text rules.
Release Notes: This release adds many bugfixes, additions, and improvements.
Release Notes: This release removes proxy information from HTTP URI searching so that the URI matches are just on the actual URI, making offsets work as expected. It addresses an issue when logging of packet data via unified2 when alerting on a packet with multiple HTTP PDUs. It will continue to search for patterns within the HTTP URI until the end of the URI.
Release Notes: This release updates file processing for partial HTTP content and MIME attachments, adds the new configuration option max_attribute_services_per_host and improves memory usage within attribute tables, handles excessive overlaps in frag3, adds Stream API updates to return a session key for a session, reduces false positives for TCP window slam events, updates to provide better encoding for TCP packets generated for "respond and react", and disables non-ethernet decoders by default (for performance reasons).
Release Notes: Consolidation of IPv6, file API and improvements to file processing, use of address space ID for tracking Frag & Stream connections, logging of packet data that triggers PPM for post-analysis, decoding of IPv6 with PPPoE, and more.
Release Notes: This release fixes a check for TCP RST flags to prevent sending resets to reset packets with inline and active responses, updates hashing for internal storage of rule options for 64bit platforms when checking uniqueness to remove duplicate copies in memory and addresses some small memory leaks from parsing snort.conf. Please note that 18.104.22.168 and later packages are signed with a new PGP key (which is signed with the previous key).
Release Notes: Updates to the flowbit rule option, dcerpc2, and reputation preprocessors. A new dynamic output plugin architecture API. Various updates and improvements to http_inspect, SMTP mempool allocations, and email attachment processing. pflog v4 support has been added to packet decoders. Logging of multiple unified2 alerts with reassembled packets has been fixed. Compiler warning cleanup across multiple platforms. All database output support has been removed.
Release Notes: The GTP preprocessor was updated to better handle GTPv1 data. The DNP3 preprocessor now has stricter packet checking. Checking in the reassembly buffer was improved. PCRE rule option processing was fixed to prevent issues seen with libpcre 8.30 and certain rules. dcerpc2 no longer aborts reassembly if the target-based protocol is undefined.
Release Notes: Updates to HTTP Inspect, stream handling for TCP session cleanup with RSTs and other TCP state tracking, active responses to fragmented IPv6 traffic and to the react page configuration, and SIP preprocessor and state tracking improvements to SMB processing in the dcerpc2 preprocessor when missing packets on a session.
