An attacker can bypass signature detection by sending a specially crafted network packet, leading to a DoS condition. This vulnerability carries a CVSS v3.0 score of 7.5 (High), indicating that it can be exploited remotely with low attack complexity, requiring no user interaction, and resulting in high availability impact. The affected components include app-layer-detect-proto.c, decode.c, decode-teredo.c, and decode-ipv6.c. There is no evidence of active exploitation, and no public exploit code (Metasploit, Nuclei, ExploitDB) is available. Community discussion and media coverage for this CVE are minimal, suggesting low public awareness. Organizations using affected Suricata versions should upgrade to 4.1.2 or later to mitigate this risk.
