From 4d42b6961af1ff14309093b4b51f74e7a84cc950 Mon Sep 17 00:00:00 2001

Subject: [PATCH] gbufferedinputstream: Fix a potential integer overflow in
peek()

If the caller provides `offset` and `count` arguments which overflow,
their sum will overflow and could lead to `memcpy()` reading out more
memory than expected.

Spotted by Codean Labs.
