Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security Monitoring engine. Prior to versions 6.0.16 and 7.0.3, an attacker can craft traffic to cause Suricata to use far more CPU and memory for processing the traffic than needed, which can lead to extreme slow downs and denial of service. This vulnerability is patched in 6.0.16 or 7.0.3. Workarounds include disabling the affected protocol app-layer parser in the yaml and reducing the `stream.reassembly.depth` value helps reduce the severity of the issue. https://github.com/OISF/suricata/commit/18841a58da71e735ddf4e52cbfa6989755ecbeb7 https://github.com/OISF/suricata/commit/2a2120ecf10c5b5713ec2bf59469fe57f7b5b747 https://github.com/OISF/suricata/commit/83c5567ea7b0b28376f57dcfee9c6301448c7bc7 https://github.com/OISF/suricata/commit/8efaebe293e2a74c8e323fa85a6f5fadf82801bc https://github.com/OISF/suricata/commit/97953998d2d60673ed6c30ddfb6a2d59b4230f97 https://github.com/OISF/suricata/commit/b1549e930f6426eeff43f12b672337cbcda566b8 https://github.com/OISF/suricata/commit/cd035d59e3df157b606f4fe67324ea8e437be786 https://github.com/OISF/suricata/commit/ce9b90326949c94a46611d6394e28600ee5e8bd5 https://github.com/OISF/suricata/commit/e7e28822f473320658d6125f16ac3f0524baff01 https://github.com/OISF/suricata/commit/f9de1cca6182e571f1c02387dca6e695e55608af https://github.com/OISF/suricata/security/advisories/GHSA-q33q-45cr-3cpc https://redmine.openinfosecfoundation.org/issues/6531 https://redmine.openinfosecfoundation.org/issues/6532 https://redmine.openinfosecfoundation.org/issues/6540 https://redmine.openinfosecfoundation.org/issues/6658 https://redmine.openinfosecfoundation.org/issues/6659 https://redmine.openinfosecfoundation.org/issues/6660
