We didn't check if the argument string is long enough before indexing into it. -- v2: xcopy: Fix out-of-bound access when parsing arguments. https://gitlab.winehq.org/wine/wine/-/merge_requests/8352

[PATCH 0/1] MR8361: shell32/tests: Fix expected ret for moving file to empty destination.
by Yuxuan Shui (＠yshui) 18 Jun '25

Related to 57817044b983683f115edea6c5068ed6cddd858b. I believe originally the missing double null terminator caused Windows to take garbage memory as file name resulted in the ERROR_FILE_NOT_FOUND. Now it's fixed we are seeing what Windows actually returns. !8316 -- https://gitlab.winehq.org/wine/wine/-/merge_requests/8361

[PATCH v2 0/1] MR8350: crypt32: Handle missing attributes in CDecodeSignedMsg_GetParam.
by Yuxuan Shui (＠yshui) 18 Jun '25

18 Jun '25

* * * While investigating another problem, I found we are handling empty attributes list differently compared native. But the actual problem is this, shouldn't `CRYPT_SizeOfAttributes` add `sizeof(CRYPT_ATTRIBUTES)` to `size`? Basically we return `size == 0` when the attributes list is empty, so the caller allocates zero bytes and call `GetParam` again, and we write out-of-bound trying to `out->cAttrs = in->cAttrs` in `CRYPT_ConstructAttributes`. (Of course with this MR this problem no longer show up, but the question still stands.) -- v2: crypt32: Handle missing attributes in CDecodeSignedMsg_GetParam. https://gitlab.winehq.org/wine/wine/-/merge_requests/8350

[PATCH v11 0/6] MR7540: kernel32/tests: Add tests for maximum path length limitation.
by Yongjie Yao (＠yaoyongjie) 18 Jun '25

18 Jun '25

In CopyFileEx, and DeleteFile functions, by default, the file name and path are limited to MAX_PATH characters. To extend this limit to 32,767 wide characters, need prepend "\\\\?\\" to the path. -- v11: kernelbase: Limit the maximum path length for DeleteFile. kernelbase: Fix DeleteFileA doesn't support long path. kernelbase: Limit the maximum path length for filesystem. ntdll: Check if long path aware is enabled. kernel32/tests: Add tests for DeleteFile kernel32/tests: Add tests for maximum path length limitation. https://gitlab.winehq.org/wine/wine/-/merge_requests/7540
