CVE-2023-2650
Description
A flaw was found in OpenSSL resulting in a possible denial of service while translating ASN.1 object identifiers. Applications that use OBJ_obj2txt() directly, or use any of the OpenSSL subsystems OCSP, PKCS7/SMIME, CMS, CMP/CRMF or TS with no message size limit may experience long delays when processing messages, which may lead to a denial of service.
Statement
CVE-2023-2650 can't cause DoS on machines with OpenSSL 1.1.1 and so is considered LOW for RHEL 8.
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).
