CVE-2023-23916
Full vulnerability record from the local CVENow database.
Description
An allocation of resources without limits or throttling vulnerability exists in curl <v7.88.0 based on the "chained" HTTP compression algorithms, meaning that a server response can be compressed multiple times and potentially with differentalgorithms. The number of acceptable "links" in this "decompression chain" wascapped, but the cap was implemented on a per-header basis allowing a maliciousserver to insert a virtually unlimited number of compression steps simply byusing many headers. The use of such a decompression chain could result in a "malloc bomb", making curl end up spending enormous amounts of allocated heap memory, or trying to and returning out of memory errors.

"value": "Una vulnerabilidad de asignación de recursos sin límites ni limitación (throttling) existe en curl anterior a v7.88.0 basada en los algoritmos de compresión HTTP 'encadenados', lo que significa que una respuesta del servidor puede ser comprimida múltiples veces y potencialmente con diferentes algoritmos. El número de 'enlaces' aceptables en esta 'cadena de descompresión' estaba limitado, pero el límite se implementó por cabecera, permitiendo a un servidor malicioso insertar un número virtualmente ilimitado de pasos de compresión simplemente usando muchas cabeceras. El uso de dicha cadena de descompresión podría resultar en una 'bomba malloc', haciendo que curl termine gastando enormes cantidades de memoria heap asignada, o intentándolo y devolviendo errores de falta de memoria."
