Threats affecting pkg:github/oisf/suricata

Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security Monitoring engine. Mishandling of multiple fragmented packets using the same IP ID value can lead to packet reassembly failure, which can lead to policy bypass. Upgrade to 7.0.6 or 6.0.20. When using af-packet, enable `defrag` to reduce the scope of the problem.

Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security Monitoring engine. Prior to 7.0.5 and 6.0.19, a small amount of HTTP/2 traffic can lead to Suricata using a large amount of memory. The issue has been addressed in Suricata 7.0.5 and 6.0.19. Workarounds include disabling the HTTP/2 parser and reducing `app-layer.protocols.http2.max-table-size` value (default is 65536).

Suricata versions prior to 6.0.13 contain a vulnerability where a dataset filename derived from a rule can cause absolute or relative directory traversal. This allows an adversary controlling an external source of rules to write to arbitrary locations on the local filesystem. The issue is fixed in version 6.0.13 by requiring explicit configuration options to allow absolute filenames and write access in dataset rules.
