AnalysisAI
The component tcpprep in Tcpreplay v4.4.1 was discovered to contain a heap-based buffer overflow in parse_mpls at common/get.c:150. Rated high severity (CVSS 7.8), this vulnerability is no authentication required, low attack complexity. Public exploit code available and no vendor patch available.
Technical ContextAI
This vulnerability is classified as Out-of-bounds Write (CWE-787), which allows attackers to write data beyond allocated buffer boundaries leading to code execution or crashes. The component tcpprep in Tcpreplay v4.4.1 was discovered to contain a heap-based buffer overflow in parse_mpls at common/get.c:150. NOTE: this is different from CVE-2022-27942. Affected products include: Broadcom Tcpreplay, Fedoraproject Fedora.
RemediationAI
No vendor patch is available at time of analysis. Monitor vendor advisories for updates. Validate write boundaries, use memory-safe languages, enable compiler protections (ASLR, stack canaries).
