Detailsinfo

A vulnerability, which was classified as critical, was found in Oracle Communications Cloud Native Core Network Exposure Function 22.4.2/23.1.0 (Cloud Software). Affected is an unknown code of the component Oracle Linux. The manipulation with an unknown input leads to a denial of service vulnerability. CWE is classifying the issue as CWE-404. The product does not release or incorrectly releases a resource before it is made available for re-use. This is going to have an impact on availability. CVE summarizes:

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.

The weakness was presented 04/18/2023 as Oracle Critical Patch Update Advisory - April 2023. The advisory is available at oracle.com. This vulnerability is traded as CVE-2023-23916. The technical details are unknown and an exploit is not available. This vulnerability is assigned to T1499 by the MITRE ATT&CK project.
