Merge #18162: util: Avoid potential uninitialized read in FormatISO8601DateTime(int64_t) by checking gmtime_s/gmtime_r return value 12a2f377185a413b740460db36812de22ee2e041 util: Avoid potential uninitialized read in FormatISO8601DateTime(int64_t nTime) by checking gmtime_s/gmtime_r return value (practicalswift) Pull request description: Avoid potential uninitialized read in `FormatISO8601DateTime(int64_t)` by checking `gmtime_s`/`gmtime_r` return value. Before this patch `FormatISO8601DateTime(67768036191676800)` resulted in: ``` ==5930== Conditional jump or move depends on uninitialised value(s) ==5930== at 0x4F44C0A: std::ostreambuf_iterator<char, std::char_traits<char> > std::num_put<char, std::ostreambuf_iterator<char, std::char_traits<char> > >::_M_insert_int<long>(std::ostreambuf_iterator<char, std::char_traits<char> >, std::ios_base&, char, long) const (in /usr/lib/x86_64-linux-gnu/libstdc++.so.6.0.25) ==5930== by 0x4F511A4: std::ostream& std::ostream::_M_insert<long>(long) (in /usr/lib/x86_64-linux-gnu/libstdc++.so.6.0.25) ==5930== by 0x4037C3: void tinyformat::formatValue<int>(std::ostream&, char const*, char const*, int, int const&) (tinyformat.h:358) ==5930== by 0x403725: void tinyformat::detail::FormatArg::formatImpl<int>(std::ostream&, char const*, char const*, int, void const*) (tinyformat.h:543) ==5930== by 0x402E02: tinyformat::detail::FormatArg::format(std::ostream&, char const*, char const*, int) const (tinyformat.h:528) ==5930== by 0x401B16: tinyformat::detail::formatImpl(std::ostream&, char const*, tinyformat::detail::FormatArg const*, int) (tinyformat.h:907) ==5930== by 0x4017AE: tinyformat::vformat(std::ostream&, char const*, tinyformat::FormatList const&) (tinyformat.h:1054) ==5930== by 0x401765: void tinyformat::format<int, int, int, int, int, int>(std::ostream&, char const*, int const&, int const&, int const&, int const&, int const&, int const&) (tinyformat.h:1064) ==5930== by 0x401656: std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > tinyformat::format<int, int, int, int, int, int>(char const*, int const&, int const&, int const&, int const&, int const&, int const&) (tinyformat.h:1073) ==5930== by 0x4014CC: FormatISO8601DateTime[abi:cxx11](long) (…) ``` The same goes for other very large positive and negative arguments. Fix by simply checking the `gmtime_s`/`gmtime_r` return value :) ACKs for top commit: MarcoFalke: ACK 12a2f377185a413b740460db36812de22ee2e041 theStack: re-ACK https://github.com/bitcoin/bitcoin/commit/12a2f377185a413b740460db36812de22ee2e041 elichai: re ACK 12a2f377185a413b740460db36812de22ee2e041 Tree-SHA512: 066142670d9bf0944d41fa3f3c702b1a460b5471b93e76a619b1e818ff9bb9c09fe14c4c37e9536a04c99533f7f21d1b08ac141e1b829ff87ee54c80d0e61d48
