Subject: [PATCH] soup-multipart: Verify array bounds before accessing its
|
||
members
|
||
|
||
The boundary could be at a place which, calculated, pointed
|
||
before the beginning of the array. Check the bounds, to avoid
|
||
read out of the array bounds.
|
||
|
||
Closes https://gitlab.gnome.org/GNOME/libsoup/-/issues/447
|
||
|
||
Upstream-Status: Backport [https://gitlab.gnome.org/GNOME/libsoup/-/commit/07b94e27afafebf31ef3cd868866a1e383750086]

Refresh the patch, remove the test part, following commit in libsoup3 has a
|
||
type refactor, which make the test is not suitable for libsoup2

[0d7e672e forms: Use GBytes instead of SoupMessageBody]
