CWEhttps://cwe.mitre.org/data/definitions/124.html

A flaw was found in GLib, which is vulnerable to an integer overflow in the g_string_insert_unichar() function. When the position at which to insert the character is large, the position will overflow, leading to a buffer underwrite.

Weakness

The product writes to a buffer using an index or pointer that references a memory location prior to the beginning of the buffer.
