HHVM 4.172.0 and all prior versions use TLS 1.0 for secure connections when handling tls:// URLs in the stream extension. TLS1.0 has numerous published vulnerabilities and is deprecated. HHVM 4.153.4, 4.168.2, 4.169.2, 4.170.2, 4.171.1, 4.172.1, 4.173.0 replaces TLS1.0 with TLS1.3. Applications that call stream_socket_server or stream_socket_client functions with a URL starting with tls:// are affected. • https://github.com/facebook/hhvm/commit/083f5ffdee661f61512909d16f9a5b98cff3cf0b https://hhvm.com/blog/2023/01/20/security-update.html •

Passing an attacker controlled size when creating an IOBuf could cause integer overflow, leading to an out of bounds write on the heap with the possibility of remote code execution. This issue affects versions of folly prior to v2021.07.22.00. This issue affects HHVM versions prior to 4.80.5, all versions between 4.81.0 and 4.102.1, all versions between 4.103.0 and 4.113.0, and versions 4.114.0, 4.115.0, 4.116.0, 4.117.0, 4.118.0 and 4.118.1. Pasar un tamaño controlado por un atacante al crear un IOBuf podría causar un desbordamiento de enteros, lo que llevaría a una escritura fuera de límites en la pila con la posibilidad de ejecución de código remoto. Este problema afecta a las versiones de folly anteriores a la v2021.07.22.00. • https://github.com/facebook/folly/commit/4f304af1411e68851bdd00ef6140e9de4616f7d3 https://hhvm.com/blog/2021/07/20/security-update.html https://www.facebook.com/security/advisories/cve-2021-24036 • CWE-122: Heap-based Buffer Overflow CWE-190: Integer Overflow or Wraparound •
