Medium [CVE-2026-58011] out-of-bounds read in glib/gdatetime.c:g_date_time_get_ymd via invalid gdatetime
CVE-2026-58011Source published Source updated
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. Any applications that allow a user to submit a date to `g_date_time_add_full()` and later call any getter functions, such as `g_date_time_get_month()` or `g_date_time_get_year()`, with the returned GDateTime object are vulnerable to this issue. This flaw can cause an out-of-bounds read of only 2 bytes, leading to a denial of service due to logic errors that a corrupted date can trigger. Due to these reasons, this vulnerability has been rated with a…

- Mitigation guidance
- 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.
