10 May 2023 — 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 • CWE-327: Use of a Broken or Risky Cryptographic Algorithm •

10 Mar 2021 — In the crypt function, we attempt to null terminate a buffer using the size of the input salt without validating that the offset is within the buffer. This issue affects HHVM versions prior to 4.56.3, all versions between 4.57.0 and 4.80.1, all versions between 4.81.0 and 4.93.1, and versions 4.94.0, 4.95.0, 4.96.0, 4.97.0, 4.98.0. En la función crypt, intentamos anular la finalización de un búfer usando el tamaño de la sal de entrada sin comprobar que el desplazamiento esté dentro del búfer.

10 Mar 2021 — Due to incorrect string size calculations inside the preg_quote function, a large input string passed to the function can trigger an integer overflow leading to a heap overflow. This issue affects HHVM versions prior to 4.56.3, all versions between 4.57.0 and 4.80.1, all versions between 4.81.0 and 4.93.1, and versions 4.94.0, 4.95.0, 4.96.0, 4.97.0, 4.98.0. Debido a cálculos de tamaño de cadena incorrectos dentro de la función preg_quote, una cadena de entrada grande pasada a la función puede desencadenar ... • https://github.com/facebook/hhvm/commit/08193b7f0cd3910256e00d599f0f3eb2519c44ca • CWE-122: Heap-based Buffer Overflow CWE-190: Integer Overflow or Wraparound •

10 Mar 2021 — xbuf_format_converter, used as part of exif_read_data, was appending a terminating null character to the generated string, but was not using its standard append char function. As a result, if the buffer was full, it would result in an out-of-bounds write. This issue affects HHVM versions prior to 4.56.3, all versions between 4.57.0 and 4.80.1, all versions between 4.81.0 and 4.93.1, and versions 4.94.0, 4.95.0, 4.96.0, 4.97.0, 4.98.0.
