Subject: [PATCH 1/6] gstrfuncs: Add internal g_memdup2() function
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
This will replace the existing `g_memdup()` function for use within
GLib. It has an unavoidable security flaw of taking its `byte_size`
argument as a `guint` rather than as a `gsize`. Most callers will
expect it to be a `gsize`, and may pass in large values which could
silently be truncated, resulting in an undersize allocation compared
to what the caller expects.
This could lead to a classic buffer overflow vulnerability for many
callers of `g_memdup()`.
`g_memdup2()`, in comparison, takes its `byte_size` as a `gsize`.
Spotted by Kevin Backhouse of GHSL.
In GLib 2.68, `g_memdup2()` will be a new public API. In this version
for backport to older stable releases, it’s a new `static inline` API
in a private header, so that use of `g_memdup()` within GLib can be
fixed without adding a new API in a stable release series.

Subject: [PATCH 2/6] glib: Use g_memdup2() instead of g_memdup() in obvious
places
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Convert all the call sites which use `g_memdup()`’s length argument
trivially (for example, by passing a `sizeof()` or an existing `gsize`
variable), so that they use `g_memdup2()` instead.
In almost all of these cases the use of `g_memdup()` would not have
caused problems, but it will soon be deprecated, so best port away from
it
In particular, this fixes an overflow within `g_bytes_new()`, identified
as GHSL-2021-045 (aka CVE-2021-27219) by GHSL team member Kevin Backhouse.
Adapted for GLib 2.58 by Simon McVittie.

From 661f5edc901219a1a99bb51f171be13063878bd6 Mon Sep 17 00:00:00 2001
From: Michael Catanzaro <mcatanzaro@redhat.com>
Date: Thu, 20 May 2021 15:58:53 -0500
Subject: [PATCH 6/6] gdatainputstream: replace easy use of g_memdup()
This code is passing a gsize, so might as well switch this to g_memdup2().
This is the only use of g_memdup() in GLib 2.56 that is not part of GLib
2.58. All other uses analyzed in glib!2000.
