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 •

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. Este problema afecta a HHVM versiones anteriores a 4.56.3, todas las versiones entre 4.57.0 y 4.80.1, todas las versiones entre 4.81.0 y 4.93.1 y versiones 4.94.0, 4.95.0, 4.96.0, 4.97.0 , 4.98.0 • https://github.com/facebook/hhvm/commit/08193b7f0cd3910256e00d599f0f3eb2519c44ca https://hhvm.com/blog/2021/02/25/security-update.html • CWE-121: Stack-based Buffer Overflow CWE-787: Out-of-bounds Write •

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 un desbordamiento de enteros que conlleva a un desbordamiento de la pila. Este problema afecta a versiones de HHVM anteriores a 4.56.3, todas las versiones entre 4.57.0 y 4.80.1, todas las versiones entre 4.81.0 y 4.93.1 y versiones 4.94.0, 4.95.0, 4.96.0, 4.97.0 , 4.98.0 • https://github.com/facebook/hhvm/commit/08193b7f0cd3910256e00d599f0f3eb2519c44ca https://hhvm.com/blog/2021/02/25/security-update.html • CWE-122: Heap-based Buffer Overflow CWE-190: Integer Overflow or Wraparound •

Incorrect bounds calculations in substr_compare could lead to an out-of-bounds read when the second string argument passed in is longer than the first. 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. Unos cálculos de límites incorrectos en la función substr_compare podrían conllevar a una lectura fuera de límites cuando el segundo argumento de cadena pasado es más largo que el primero. Este problema afecta a HHVM versiones anteriores a 4.56.3, todas las versiones entre 4.57.0 y 4.80.1, todas las versiones entre 4.81.0 y 4.93.1 y las versiones 4.94.0, 4.95.0, 4.96.0, 4.97.0 , 4.98.0 • https://github.com/facebook/hhvm/commit/08193b7f0cd3910256e00d599f0f3eb2519c44ca https://hhvm.com/blog/2021/02/25/security-update.html • CWE-125: Out-of-bounds Read •
