CVSS: 7.5EPSS: 0%CPEs: 9EXPL: 0CVE-2023-38403 – iperf3: memory allocation hazard and crash
https://notcve.org/view.php?id=CVE-2023-38403
iperf3 before 3.14 allows peers to cause an integer overflow and heap corruption via a crafted length field. An integer overflow flaw was found in the way iperf3 dynamically allocates memory buffers for JSON-formatted messages. A remote attacker could send a specially crafted sequence of bytes on the iperf3 control channel with a specified JSON message length of 0xffffffff to trigger an integer overflow leading the receiving process to abort due to heap corruption. This flaw allows an attacker to use a malicious client to cause a denial of service of an iperf3 server or potentially use a malicious server to cause connecting clients to crash. • http://seclists.org/fulldisclosure/2023/Oct/24 http://seclists.org/fulldisclosure/2023/Oct/26 https://bugs.debian.org/1040830 https://cwe.mitre.org/data/definitions/130.html https://downloads.es.net/pub/iperf/esnet-secadv-2023-0001.txt.asc https://github.com/esnet/iperf/commit/0ef151550d96cc4460f98832df84b4a1e87c65e9 https://github.com/esnet/iperf/issues/1542 https://lists.debian.org/debian-lts-announce/2023/07/msg00025.html https://lists.fedoraproject.org/archives/list/package-announce% • CWE-190: Integer Overflow or Wraparound •
CVSS: 9.8EPSS: 1%CPEs: 6EXPL: 2CVE-2016-4303
https://notcve.org/view.php?id=CVE-2016-4303
The parse_string function in cjson.c in the cJSON library mishandles UTF8/16 strings, which allows remote attackers to cause a denial of service (crash) or execute arbitrary code via a non-hex character in a JSON string, which triggers a heap-based buffer overflow. La función parse_string en cjson.c en la librería cJSON no maneja correctamente cadenas UTF8/16, lo que permite a atacantes remotos provocar una denegación de servicio (caída) o ejecutar código arbitrario a través de un carácter no hexadecimal en una cadena JSON, lo que desencadena un desbordamiento de búfer basado en memoria dinámica. • http://blog.talosintel.com/2016/06/esnet-vulnerability.html http://lists.opensuse.org/opensuse-updates/2016-08/msg00082.html http://lists.opensuse.org/opensuse-updates/2016-08/msg00090.html http://software.es.net/iperf/news.html#security-issue-iperf-3-1-3-iperf-3-0-12-released http://www.talosintelligence.com/reports/TALOS-2016-0164 https://github.com/esnet/iperf/commit/91f2fa59e8ed80dfbf400add0164ee0e508e412a https://lists.debian.org/debian-lts-announce/2020/01/msg00023.html https://raw.github • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') •
