CVE-2024-2398
Description
A flaw was found in curl. When an application configures libcurl to use HTTP/2 server push and the amount of received headers for the push surpasses the maximum allowed limit, libcurl aborts the server push. When aborting, libcurl does not free all the previously allocated headers, resulting in a memory leak.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
