Summary
[none]
Details

A flaw was found in glib. Missing validation of offset and count parameters in the gbufferedinputstreampeek() function can lead to an integer overflow during length calculation. When specially crafted values are provided, this overflow results in an incorrect size being passed to memcpy(), triggering a buffer overflow. This can cause application crashes, leading to a Denial of Service (DoS).
