| 4 | Subject: [PATCH] Bugfix and optimize archive_wstring_append_from_mbs() | ||
| 5 | |||
| 6 | The cal to mbrtowc() or mbtowc() should read up to mbs_length | ||
| 7 | bytes and not wcs_length. This avoids out-of-bounds reads. | ||
| 8 | |||
| 9 | mbrtowc() and mbtowc() return (size_t)-1 wit errno EILSEQ when | ||
| 10 | they encounter an invalid multibyte character and (size_t)-2 when | ||
| 11 | they they encounter an incomplete multibyte character. As we return | ||
| 12 | failure and all our callers error out it makes no sense to continue | ||
| 13 | parsing mbs. | ||
| 14 | |||
| 15 | As we allocate `len` wchars at the beginning and each wchar has | ||
| 16 | at least one byte, there will never be need to grow the buffer, | ||
| 17 | so the code can be left out. On the other hand, we are always | ||
| 18 | allocatng more memory than we need. | ||
| 19 | |||
| 20 | As long as wcs_length == mbs_length == len we can omit wcs_length. | ||
| 21 | We keep the old code commented if we decide to save memory and | ||
| 22 | use autoexpanding wcs_length in the future. | ||
| 23 | |||
| 24 | Fixes #1276 | ||
| 25 | |||
