Summary

An integer overflow vulnerability exists in the GLib library prior to version 2.66.6 and in the series 2.67.x before 2.67.3. This issue arises from an implicit cast from 64-bit integers to 32-bit during the execution of the g_bytes_new function, which may lead to memory corruption. Exploiting this vulnerability could result in unexpected behavior, including potential denial of service or code execution on affected systems.
