When hashing empty dict strings in a crafted XML document, xmlDictComputeFastKey in dict.c can produce non-deterministic values, leading to various logic and memory errors, such as a double free. This behavior occurs because there is an attempt to use the first byte of an empty string, and any value is possible (not solely the '\\0' value).","modified":"2025-11-06T23:03:18.328627Z","published":"2025-10-17T17:40:51.659Z","upstream":["CVE-2023-29469"],"database_specific":{"sources":[{"html_url":"https://nvd.nist.gov/vuln/detail/CVE-2023-29469","url":"https://services.nvd.nist.gov/rest/json/cves/2.0?cveId=CVE-2023-29469","imported":"2025-10-28T18:09:09.633Z","published":"2023-04-24T21:15:09.230Z","id":"CVE-2023-29469","modified":"2025-02-04T21:15:23.447Z"}],"license":"CC-BY-4.0"},"references":[{"type":"WEB","url":"https://gitlab.gnome.org/GNOME/libxml2/-/issues/510"},{"type":"WEB","url":"https://gitlab.gnome.org/GNOME/libxml2/-/releases/v2.10.4"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2023/04/msg00031.html"},{"type":"WEB","url":"https://security.netapp.com/advisory/ntap-20230601-0006/"}],"affected":[{"package":{"name":"XML2_jll","ecosystem":"Julia","purl":"pkg:julia/XML2_jll?uuid=02c8fc9c-b97f-50b9-bbe4-9be30ff0a78a"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"2.10.4+0"},{"introduced":"2.11.5+0"},{"fixed":"2.12.0+0"}]}],"database_specific":{"source":"https://github.com/JuliaLang/SecurityAdvisories.jl/tree/generated/osv/2025/JLSEC-2025-80.json"}}],"schema_version":"1.7.3"}
