Description Dhananjay Arunesh 2023-03-23 09:55:46 UTC 
A vulnerability was found in GLib2.0, where denial of service caused by handling a malicious serialised variant which is structured to cause allocations or looping superlinear to its serialised size. Applications are at risk if they accept untrusted serialised variants by checking them with g_variant_get_normal_form() (or don’t check them).
