CVE-2024-55627
CVE-2024-55627 affects Suricata, a network intrusion detection system. This vulnerability allows a specially crafted TCP stream to trigger a buffer overflow.
CVE-2024-55627 is a buffer overflow vulnerability in Suricata versions prior to 7.0.8 caused by an unsigned integer underflow during the zero-filling initialization of a TCP stream. An attacker can exploit this by sending a malicious TCP stream, leading to potential denial of service or potentially arbitrary code execution. Although the CVSS score is 7.5, the SVRS score of 56 indicates a moderate risk. Users of Suricata should upgrade to version 7.0.8 to mitigate this threat, preventing attackers from leveraging the buffer overflow. The presence of "In The Wild" tag, highlights the importance of prompt patching.
Description
CVE-2024-55627 affects Suricata, a popular network intrusion detection and prevention system. This vulnerability allows attackers to exploit an unsigned integer underflow during initialization, leading to a very large buffer overflow. The vulnerability is triggered by a specially crafted TCP stream that causes a memory allocation error, potentially resulting in denial of service, code execution, or other security compromises. While the CVSS score is 5.9, the SOCRadar Vulnerability Risk Score (SVRS) is 38, suggesting a moderate risk level requiring attention.
