The function xmlSnprintfElementContent in valid.c is supposed to recursively dump the element content definition into a char buffer 'buf' of size 'size'. At the end of the routine, the function may strcat two more characters without checking whether the current strlen(buf) + 2 < size. This vulnerability causes programs that use libxml2, such as PHP, to crash.","published_at":"2017-05-18T06:13:00Z","last_modified_at":"2026-10-14T07:16:40.950000Z","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","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-119"],"nvd_references":["http://www.debian.org/security/2017/dsa-3952","https://security.gentoo.org/glsa/201711-01","http://www.openwall.com/lists/oss-security/2017/05/15/1","http://www.securityfocus.com/bid/98556","https://lists.apache.org/thread.html/rf4c02775860db415b4955778a131c2795223f61cb8c6a450893651e4%40%3Cissues.bookkeeper.apache.org%3E","https://lists.apache.org/thread.html/r58af02e294bd07f487e2c64ffc0a29b837db5600e33b6e698b9d696b%40%3Cissues.bookkeeper.apache.org%3E"],"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":"2026-10-14T23:59:09.254433Z"},"effective_severity":"HIGH","badges":[],"impact_analysis":[],"cvss_v3_decoded":{"version":"3.1","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":"xmlsoft","vendor_name":"xmlsoft","product_slug":"libxml2","product_name":"libxml2","version_start":"2.9.4","version_start_inclusive":true,"version_end":"2.9.4","version_end_inclusive":true,"cpe23_uri":"cpe:2.3:a:xmlsoft:libxml2:2.9.4:*:*:*:*:*:*:*"}],"exploit_refs":[],"news":[],"references":[{"url":"http://www.debian.org/security/2017/dsa-3952","source_type":"VENDOR_ADVISORY","tags":["advisory"]},{"url":"https://security.gentoo.org/glsa/201711-01","source_type":"MISC","tags":[]},{"url":"http://www.openwall.com/lists/oss-security/2017/05/15/1","source_type":"MAILING_LIST","tags":["mailing-list"]},{"url":"http://www.securityfocus.com/bid/98556","source_type":"MISC","tags":[]},{"url":"https://lists.apache.org/thread.html/rf4c02775860db415b4955778a131c2795223f61cb8c6a450893651e4%40%3Cissues.bookkeeper.apache.org%3E","source_type":"MAILING_LIST","tags":["mailing-list"]},{"url":"https://lists.apache.org/thread.html/r58af02e294bd07f487e2c64ffc0a29b837db5600e33b6e698b9d696b%40%3Cissues.bookkeeper.apache.org%3E","source_type":"MAILING_LIST","tags":["mailing-list"]}],"timeline":[{"type":"published","at":"2017-05-18T06:13:00Z","label":"CVE published","source":null},{"type":"ssvc_changed","at":"2026-06-24T00:31:10.389451Z","label":"SSVC decision revised","source":"vulnrichment"},{"type":"ssvc_changed","at":"2026-06-24T00:31:10.389451Z","label":"SSVC decision revised","source":"vulnrichment"},{"type":"ssvc_changed","at":"2026-06-24T00:31:10.389451Z","label":"SSVC decision revised","source":"vulnrichment"},{"type":"cvss_changed","at":"2026-06-24T00:31:10.389451Z","label":"CVSS score revised","source":"vulnrichment"},{"type":"cvss_changed","at":"2026-06-24T00:31:10.389451Z","label":"CVSS score revised","source":"vulnrichment"},{"type":"cvss_changed","at":"2026-06-24T00:31:10.389451Z","label":"CVSS score revised","source":"vulnrichment"}]}
