  "details" : [ "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.", "A flaw was found in the Curl package. A malicious server can insert an unlimited number of compression steps. This decompression chain could result in out-of-memory errors." ],
