REF:https://bugzilla.tianocore.org/show_bug.cgi?id=1279 For function ResolveSymlink(), the below codes: if (CompareMem ((VOID *)&PreviousFile, (VOID *)Parent, sizeof (UDF_FILE_INFO)) != 0) { CleanupFileInformation (&PreviousFile); } CopyMem ((VOID *)&PreviousFile, (VOID *)File, sizeof (UDF_FILE_INFO)); If the contents in 'PreviousFile' and 'File' are the same, call to "CleanupFileInformation (&PreviousFile);" will free the buffers in 'File' as well. This will lead to potential memory double free/use after free issues. This commit will add additional check to address the above issue.
