Database corruption via freed asynchronous write buffer
Published Dec 26, 2022 · Updated Aug 5, 2024
Use-after-free in GNOME GVDB allows remote attackers to corrupt database output through asynchronous writes after user interaction. In gvdb_table_write_contents_async, gvdb-builder.c frees the GString and then passes its str and len fields to g_file_replace_contents_async instead of using the retained GBytes data. Reachability depends on an embedding application invoking the asynchronous writer with attacker-influenced data; the confirmed operational consequence is an empty saved file.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
