O problema está relacionado a uma gravação fora dos limites na função `WavPackSamples`, no arquivo `pack utils.c`, devido a um estouro de inteiro em um argumento da função `malloc`. Isso pode permitir que um invasor remoto comprometa a integridade dos dados e cause uma negação de serviço.

Name of the Vulnerable Software and Affected Versions: Suricata versions prior to 4.1.2 Description: The issue allows an attacker to evade signature detection by sending a specially formed network packet, potentially bypassing DNS detection. This is achieved through a Denial of Service attack. The components affected are app-layer-detect-proto.c, decode.c, decode-teredo.c, and decode-ipv6.c. An attacker can trigger this issue by sending a specifically crafted network request. Recommendations: For Suricata versions prior to 4.1.2, update to version 4.1.2 to resolve the issue. As a temporary workaround, consider restricting access to the affected components until the update can be applied.

Name of the Vulnerable Software and Affected Versions: Suricata versions prior to 4.1.3 Description: The issue allows an attacker to bypass signature detection using a specially formed sequence of network packets, potentially evading detection. This can be triggered by an attacker through a specifically crafted network TCP session. Recommendations: For versions prior to 4.1.3, update to version 4.1.3 to resolve the issue. As a temporary workaround, consider restricting access to detect.c component until the update is applied.
