The affected application contains an out of bounds write past the end of an allocated buffer when handling specific requests on port 4002/tcp and 4004/tcp. This could allow an attacker to crash the application. The corresponding service is auto-restarted after the crash.","published_at":"2023-12-12T11:27:15.737000Z","last_modified_at":null,"cvss_v3_score":7.5,"cvss_v3_vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H/E:P/RL:O/RC:C","cvss_v3_severity":"HIGH","cvss_v4_score":null,"cvss_v4_vector":null,"cvss_v4_severity":null,"ssvc_decision":null,"ssvc_exploitation":"none","ssvc_automatable":true,"ssvc_technical_impact":"partial","cwes":["CWE-120"],"nvd_references":["https://cert-portal.siemens.com/productcert/pdf/ssa-999588.pdf","https://cert-portal.siemens.com/productcert/html/ssa-999588.html"],"vuln_status":null,"trending_score":null,"is_trending":false,"has_trended":false,"trended_number_one":false,"trending_peak_score":null,"trending_peak_rank":null,"started_trending_at":null,"trended_number_one_at":null,"summary_generated":null,"summary_generated_at":null,"summary_model":null,"created_at":"2026-06-24T00:09:39.878444Z","updated_at":"2026-06-29T01:39:28.500535Z"},"effective_severity":"HIGH","badges":[],"impact_analysis":[],"cvss_v3_decoded":{"version":"3.1","metrics":[{"metric":"AV","name":"Attack
