GLib Integer Overflow Vulnerability in g_buffered_input_stream_peek() Function Leading to Buffer Overflow

A vulnerability exists in the GLib library due to inadequate validation of offset and count parameters in the g_buffered_input_stream_peek() function. This oversight can cause an integer overflow during length calculations. When specially crafted values are used, the overflow leads to an incorrect size being passed to memcpy(), resulting in a buffer overflow. Such exploitation can cause application crashes, creating a Denial of Service (DoS) condition.

Impact

Exploitation of this vulnerability causes application crashes and instability, leading to a Denial of Service (DoS) condition. Additionally, the buffer overflow could be exploited to execute unauthorized code or commands, bypassing protection mechanisms.
