{"id":"UBUNTU-CVE-2025-7039","details":"A flaw was found in glib. An integer overflow during temporary file creation leads to an out-of-bounds memory access, allowing an attacker to potentially perform path traversal or access private temporary file content by creating symbolic links. This vulnerability allows a local attacker to manipulate file paths and access unauthorized data. The core issue stems from insufficient validation of file path lengths during temporary file operations.","modified":"2026-04-22T16:14:00.119362Z","published":"2025-09-03T02:15:00Z","related":["USN-7942-1","USN-7942-2"],"upstream":["CVE-2025-7039"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2025-7039"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2025-7039"},{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-7942-1"},{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-7942-2"}],"affected":[{"package":{"name":"glib2.0","ecosystem":"Ubuntu:Pro:14.04:LTS","purl":"pkg:deb/ubuntu/glib2.0@2.40.2-0ubuntu1.1+esm7?arch=source&distro=esm-infra-legacy/trusty"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.40.2-0ubuntu1.1+esm7"}]}],"versions":["2.38.0-1ubuntu1","2.38.1-1","2.39.1-0ubuntu1","2.39.1-0ubuntu2","2.39.1-0ubuntu3","2.39.2-0ubuntu1","2.39.2-0ubuntu2","2.39.3-0ubuntu4","2.39.4-0ubuntu1","2.39.90-0ubuntu1","2.39.91-0ubuntu2","2.39.91-0ubuntu3","2.39.92-2","2.40.0-1","2.40.0-1ubuntu1","2.40.0-2","2.40.2-0ubuntu1","2.40.2-0ubuntu1.1","2.40.2-0ubuntu1.1+esm1","2.40.2-0ubuntu1.1+esm2","2.40.2-0ubuntu1.1+esm3","2.40.2-0ubuntu1.1+esm4","2.40.2-0ubuntu1.1+esm6"],"ecosystem_specific":{"availability":"Available
