Writes that start from the second-to-last position of a buffer cause a miscalculation of the maximum length of the input bytes to be written.","published_at":"2018-08-21T13:00:00Z","last_modified_at":"2026-10-15T18:17:11.007000Z","cvss_v3_score":7.5,"cvss_v3_vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","cvss_v3_severity":"HIGH","cvss_v4_score":null,"cvss_v4_vector":null,"cvss_v4_severity":null,"ssvc_decision":null,"ssvc_exploitation":null,"ssvc_automatable":null,"ssvc_technical_impact":null,"cwes":["CWE-787"],"nvd_references":["http://www.securityfocus.com/bid/105127","https://access.redhat.com/errata/RHSA-2018:2552","https://access.redhat.com/errata/RHSA-2018:2553","https://access.redhat.com/errata/RHSA-2018:2944","https://nodejs.org/en/blog/vulnerability/august-2018-security-releases/","https://access.redhat.com/errata/RHSA-2018:3537","https://access.redhat.com/errata/RHSA-2018:2949","https://security.gentoo.org/glsa/202003-48"],"vuln_status":"Modified","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":"2026-10-18T16:57:00.340492Z"},"effective_severity":"HIGH","badges":[],"impact_analysis":[],"cvss_v3_decoded":{"version":"3.0","metrics":[{"metric":"AV","name":"Attack Vector","value":"N","value_label":"Network"},{"metric":"AC","name":"Attack Complexity","value":"L","value_label":"Low"},{"metric":"PR","name":"Privileges Required","value":"N","value_label":"None"},{"metric":"UI","name":"User Interaction","value":"N","value_label":"None"},{"metric":"S","name":"Scope","value":"U","value_label":"Unchanged"},{"metric":"C","name":"Confidentiality","value":"N","value_label":"None"},{"metric":"I","name":"Integrity","value":"N","value_label":"None"},{"metric":"A","name":"Availability","value":"H","value_label":"High"}]},"cvss_v4_decoded":{"version":null,"metrics":[]},"affected":[{"vendor_slug":"nodejs","vendor_name":"nodejs","product_slug":"node.js","product_name":"node.js","version_start":null,"version_start_inclusive":null,"version_end":"6.14.4","version_end_inclusive":false,"cpe23_uri":"cpe:2.3:a:nodejs:node.js:*:*:*:*:*:*:*:*"},{"vendor_slug":"redhat","vendor_name":"redhat","product_slug":"openshift-container-platform","product_name":"openshift_container_platform","version_start":"3.11","version_start_inclusive":true,"version_end":"3.11","version_end_inclusive":true,"cpe23_uri":"cpe:2.3:a:redhat:openshift_container_platform:3.11:*:*:*:*:*:*:*"},{"vendor_slug":"the-node.js-project","vendor_name":"The Node.js Project","product_slug":"node.js","product_name":"Node.js","version_start":"All versions of Node.js prior to 6.14.4, 8.11.4 and 10.9.0","version_start_inclusive":true,"version_end":"All versions of Node.js prior to 6.14.4, 8.11.4 and 10.9.0","version_end_inclusive":true,"cpe23_uri":"cve5:the-node.js-project:node.js:All versions of Node.js prior to 6.14.4, 8.11.4 and 10.9.0:All versions of Node.js prior to 6.14.4, 8.11.4 and 10.9.0"}],"exploit_refs":[],"news":[],"references":[{"url":"http://www.securityfocus.com/bid/105127","source_type":"MISC","tags":[]},{"url":"https://access.redhat.com/errata/RHSA-2018:2552","source_type":"VENDOR_ADVISORY","tags":["advisory"]},{"url":"https://access.redhat.com/errata/RHSA-2018:2553","source_type":"VENDOR_ADVISORY","tags":["advisory"]},{"url":"https://access.redhat.com/errata/RHSA-2018:2944","source_type":"VENDOR_ADVISORY","tags":["advisory"]},{"url":"https://nodejs.org/en/blog/vulnerability/august-2018-security-releases/","source_type":"MISC","tags":[]},{"url":"https://access.redhat.com/errata/RHSA-2018:3537","source_type":"VENDOR_ADVISORY","tags":["advisory"]},{"url":"https://access.redhat.com/errata/RHSA-2018:2949","source_type":"VENDOR_ADVISORY","tags":["advisory"]},{"url":"https://security.gentoo.org/glsa/202003-48","source_type":"MISC","tags":[]}],"timeline":[{"type":"published","at":"2018-08-21T13:00:00Z","label":"CVE published","source":null},{"type":"cvss_changed","at":"2026-10-18T16:57:00.340492Z","label":"CVSS score revised","source":"nvd"},{"type":"cvss_changed","at":"2026-10-18T16:57:00.340492Z","label":"CVSS score revised","source":"nvd"},{"type":"cvss_changed","at":"2026-10-18T16:57:00.340492Z","label":"CVSS score revised","source":"nvd"}]}
