{"id":"UBUNTU-CVE-2025-9714","details":"Uncontrolled recursion in XPath evaluation in libxml2 up to and including version 2.9.14 allows a local attacker to cause a stack overflow via crafted expressions. XPath processing functions `xmlXPathRunEval`, `xmlXPathCtxtCompile`, and `xmlXPathEvalExpr` were resetting recursion depth to zero before making potentially recursive calls. When such functions were called recursively this could allow for uncontrolled recursion and lead to a stack overflow. These functions now preserve recursion depth across recursive calls, allowing recursion depth to be controlled.","modified":"2026-04-22T16:16:43.278493Z","published":"2025-09-04T00:00:00Z","related":["USN-7743-1"],"upstream":["CVE-2025-9714"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2025-9714"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2025-9714"},{"type":"REPORT","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2392605"},{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-7743-1"}],"affected":[{"package":{"name":"libxml2","ecosystem":"Ubuntu:Pro:14.04:LTS","purl":"pkg:deb/ubuntu/libxml2@2.9.1+dfsg1-3ubuntu4.13+esm9?arch=source&distro=esm-infra-legacy/trusty"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.9.1+dfsg1-3ubuntu4.13+esm9"}]}],"versions":["2.9.1+dfsg1-3ubuntu2","2.9.1+dfsg1-3ubuntu3","2.9.1+dfsg1-3ubuntu4","2.9.1+dfsg1-3ubuntu4.1","2.9.1+dfsg1-3ubuntu4.2","2.9.1+dfsg1-3ubuntu4.3","2.9.1+dfsg1-3ubuntu4.4","2.9.1+dfsg1-3ubuntu4.5","2.9.1+dfsg1-3ubuntu4.6","2.9.1+dfsg1-3ubuntu4.7","2.9.1+dfsg1-3ubuntu4.8","2.9.1+dfsg1-3ubuntu4.9","2.9.1+dfsg1-3ubuntu4.10","2.9.1+dfsg1-3ubuntu4.11","2.9.1+dfsg1-3ubuntu4.12","2.9.1+dfsg1-3ubuntu4.13","2.9.1+dfsg1-3ubuntu4.13+esm1","2.9.1+dfsg1-3ubuntu4.13+esm2","2.9.1+dfsg1-3ubuntu4.13+esm3","2.9.1+dfsg1-3ubuntu4.13+esm4","2.9.1+dfsg1-3ubuntu4.13+esm5","2.9.1+dfsg1-3ubuntu4.13+esm6","2.9.1+dfsg1-3ubuntu4.13+esm7","2.9.1+dfsg1-3ubuntu4.13+esm8"],"ecosystem_specific":{"availability":"Available
