Description
A flaw was found in GLib. An out-of-bounds read of only 2 bytes can occur in the g_date_time_get_ymd function in the glib/gdatetime.c file when an invalid GDateTime object produced by the g_date_time_add_full function is processed. This flaw can corrupt the date output and potentially cause logic errors that may lead to a denial of service.

Remediation

Vendor Workaround

To mitigate this vulnerability, in applications processing user-supplied dates, implement input validation to ensure the supplied date is within the supported range before calling g_date_time_add_full() with untrusted data, specifically rejecting inputs that result in a negative or zero days field.
