Detailsinfo

A vulnerability, which was classified as critical, has been found in Oracle Communications Cloud Native Core Unified Data Repository 22.4.1 (Cloud Software). Affected by this issue is an unknown code block of the component Signaling. The manipulation with an unknown input leads to a denial of service vulnerability. Using CWE to declare the problem leads to CWE-404. The product does not release or incorrectly releases a resource before it is made available for re-use. Impacted is 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 released 04/18/2023 as Oracle Critical Patch Update Advisory - April 2023. The advisory is available at oracle.com. This vulnerability is handled 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.
