What is CVE-2025-7039?

A significant flaw has been identified in GLib, relating to an integer overflow during the creation of temporary files. This defect can lead to out-of-bounds memory access, thus allowing local attackers to manipulate file paths effectively. The flaw stems from inadequate validation of file path lengths in temporary file operations, enabling unauthorized access to sensitive content through the creation of symbolic links. Attackers could exploit this vulnerability to execute path traversal attacks and gain access to private data stored in temporary files.
