Glib: buffer under-read on glib through glib/gfileutils.c via get_tmp_file()
CVE-2025-7039 is fixed in 13 products on 1 platform, first by DEBIAN-CVE-2025-7039, released September 3, 2025. It is not reported as exploited. Patch Radar priority: Routine.
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.
