From 024eec02a59d5902e3731a7120ebc97846b34991 Mon Sep 17 00:00:00 2001 From: Lioncash Date: Wed, 3 Oct 2018 02:13:49 -0400 Subject: submission_package: Avoid dangling std::string_view within SetTicketKeys() GetName() returns a std::string by value, not by reference, so after the std::string_view is constructed, it's not well defined to actually execute any member functions of std::string_view that attempt to access the data, as the std::string has already been destroyed. Instead, we can just use a std::string and erase the last four characters. --- src/core/file_sys/submission_package.cpp | 7 +++++-- 1 file changed, 5 insertions(+), 2 deletions(-) (limited to 'src/core') diff --git a/src/core/file_sys/submission_package.cpp b/src/core/file_sys/submission_package.cpp index 829aca06f..09bf077cd 100644 --- a/src/core/file_sys/submission_package.cpp +++ b/src/core/file_sys/submission_package.cpp @@ -38,8 +38,11 @@ void SetTicketKeys(const std::vector& files) { Core::Crypto::Key128 key{}; ticket_file->Read(key.data(), key.size(), Core::Crypto::TICKET_FILE_TITLEKEY_OFFSET); - std::string_view name_only(ticket_file->GetName()); - name_only.remove_suffix(4); + + // We get the name without the extension in order to create the rights ID. + std::string name_only(ticket_file->GetName()); + name_only.erase(name_only.size() - 4); + const auto rights_id_raw = Common::HexStringToArray<16>(name_only); u128 rights_id; std::memcpy(rights_id.data(), rights_id_raw.data(), sizeof(u128)); -- cgit v1.2.3
