CVE-2024-24989
Description
A flaw was found in the nginx HTTP/3 implementation. This issue may allow an attacker to use a specially crafted QUIC session to trigger a NULL pointer dereference error, causing a worker process to crash, leading to a denial of service.
Statement
The nginx package as shipped in Red Hat Enterprise Linux 8, 9 and RHSCL is not affected by this vulnerability because support for HTTP3 is not enabled and the vulnerable code was introduced in a newer version of nginx.
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).
The following CVSS metrics and score provided are preliminary and subject to review.
