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.

Affected configurations

• haxx curl (>= 7.57.0 < 7.88.0) • fedoraproject fedora 36 • debian debian linux 10.0 • debian debian linux 11.0 • netapp h300s firmware • netapp h500s firmware • netapp h700s firmware • netapp h410s firmware • netapp clustered data ontap • splunk universal forwarder (>= 8.2.0 < 8.2.12) • splunk universal forwarder (>= 9.0.0 < 9.0.6) • splunk universal forwarder 9.1.0
