{"id":"UBUNTU-CVE-2025-11731","details":"A flaw was found in the exsltFuncResultComp() function of libxslt, which handles EXSLT \u003cfunc:result\u003e elements during stylesheet parsing. Due to improper type handling, the function may treat an XML document node as a regular XML element node, resulting in a type confusion. This can cause unexpected memory reads and potential crashes. While difficult to exploit, the flaw could lead to application instability or denial of service.","modified":"2026-05-20T16:10:08.944215390Z","published":"2025-10-14T06:15:00Z","upstream":["CVE-2025-11731"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2025-11731"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2025-11731"},{"type":"REPORT","url":"https://access.redhat.com/security/cve/CVE-2025-11731"}],"affected":[{"package":{"name":"libxslt","ecosystem":"Ubuntu:Pro:14.04:LTS","purl":"pkg:deb/ubuntu/libxslt?arch=source&distro=esm-infra-legacy%2Ftrusty"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.1.28-2","1.1.28-2build1","1.1.28-2ubuntu0.1","1.1.28-2ubuntu0.2","1.1.28-2ubuntu0.2+esm1","1.1.28-2ubuntu0.2+esm2","1.1.28-2ubuntu0.2+esm3","1.1.28-2ubuntu0.2+esm4","1.1.28-2ubuntu0.2+esm5"],"ecosystem_specific":{"priority_reason":"Upstream
