CVE-2023-23916 is an allocation of resources without limits vulnerability in curl versions prior to 7.88.0, affecting products like Debian, Fedora, NetApp, and Splunk. A malicious server can trigger a "malloc bomb" by chaining multiple HTTP compression algorithms, leading to excessive memory allocation and potential denial of service. With a CVSS score of 6.5 (Medium), this vulnerability requires user interaction (UI:R) but has a high impact on availability (A:H). There is currently no evidence of active exploitation, public exploit code, or significant community discussion surrounding this CVE.

Aug 30, 2023curl: HTTP multi-header compression denial of service
Feb 15, 2023HTTP multi-header compression denial of service
Feb 15, 2023An 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.
