CVE-2023-24609

  1. OpenCVE
  2. Vulnerabilities (CVE)
  3. CVE-2023-24609
Matrix SSL 4.x through 4.6.0 and Rambus TLS Toolkit have a length-subtraction integer overflow for Client Hello Pre-Shared Key extension parsing in the TLS 1.3 server. An attacked device calculates an SHA-2 hash over at least 65 KB (in RAM). With a large number of crafted TLS messages, the CPU becomes heavily loaded. This occurs in tls13VerifyBinder and tls13TranscriptHashUpdate.

Summary
  • (es) Matrix SSL 4.x a 4.6.0 y Rambus TLS Toolkit tienen un desbordamiento de enteros de sustracción de longitud para el análisis de la extensión Client Hello Pre-Shared Key en el servidor TLS 1.3. Un dispositivo atacado calcula un hash SHA-2 en al menos 65 KB (en RAM). Con una gran cantidad de mensajes TLS manipulados, la CPU se carga mucho. Esto ocurre en tls13VerifyBinder y tls13TranscriptHashUpdate.
