Name of the Vulnerable Software and Affected Versions Suricata versions prior to 7.0.3

Description The issue is related to a heap use after free condition that can be triggered by specially crafted traffic when the ruleset uses the http.request header or http.response header keyword. This can potentially allow a remote attacker to impact the integrity and availability of protected information.

Recommendations To resolve the issue, update to version 7.0.3 or later. As a temporary workaround, consider avoiding the use of the http.request header and http.response header keywords in the ruleset until a patch is applied.
