Doc Text:
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.

Description OSIDB Bzimport 2025-09-01 16:26:26 UTC
An integer overflow in glib's temporary directory/file creation allows an out of boundary access, which might be used by an attacker to perform path traversal or access to private content of a temporary file by creating symbolic links which an affected application would follow.
