OpenSSL 1.1.1l (64-bit) 軟體資訊介紹&下載

Arduino,軟體教學,軟體下載,電腦問題,電腦教學
開放源代碼 Arduino 軟件(IDE)可以輕鬆編寫代碼並將其上傳到開發板。它運行在 Windows,Mac OS X 和 Linux 上。環境是用 Java 編寫的,基於 Processing 和其他開源軟件。這個軟件可以與任何 Arduino 板一起使用。

最有趣的功能是:

等待新的 arduino-builder
這是一個純粹的命令行工具,它負責修改代碼,解決庫依賴和設置編譯單元。它也可以作為一個獨立的程序在一個持續集成的環境中.

可插拔的 USB 核心
你的 Arduino 終於可以作為很多不同的 USB 設備,而無需改變核心,這要歸功於新的模塊化架構。基於新子系統的庫已經在開發中!

串口繪圖儀
您現在可以實時繪製您的數據,就像在您的循環內寫入 Serial.println(analogRead(A0))一樣簡單.

新的好東西
對於圖書館開發人員,並可選擇鏈接到檔案中。

ArduinoISP 示例
已經改進了很多,現在您可以使用任何其他闆卡來刷新 AVR 芯片。

圖書館和書庫管理員
如果圖書館 / 核心可以通過簡單的彈出式菜單更新,請通知我們。沒有更多過時的代碼浮動!

注意:需要 Arduino 平台.

What's new in this version:

Fixed an SM2 Decryption Buffer Overflow:
- In order to decrypt SM2 encrypted data an application is expected to call the API function EVP_PKEY_decrypt(). Typically an application will call this function twice. The first time, on entry, the "out" parameter can be NULL and, on exit, the "outlen" parameter is populated with the buffer size required to hold the decrypted plaintext. The application can then allocate a sufficiently sized buffer and call EVP_PKEY_decrypt() again, but this time passing a non-NULL value for the "out" parameter.
- A bug in the implementation of the SM2 decryption code means that the calculation of the buffer size required to hold the plaintext returned by the first call to EVP_PKEY_decrypt() can be smaller than the actual size required by the second call. This can lead to a buffer overflow when EVP_PKEY_decrypt() is called by the application a second time with a buffer that is too small.
- A malicious attacker who is able present SM2 content for decryption to an application could cause attacker chosen data to overflow the buffer by up to a maximum of 62 bytes altering the contents of other data held after the buffer, possibly changing application behaviour or causing the application to crash. The location of the buffer is application dependent but is typically heap allocated.

Fixed various read buffer overruns processing ASN.1 strings:
- ASN.1 strings are represented internally within OpenSSL as an ASN1_STRING structure which contains a buffer holding the string data and a field holding the buffer length. This contrasts with normal C strings which are repesented as a buffer for the string data which is terminated with a NUL (0) byte.
- Although not a strict requirement, ASN.1 strings that are parsed using OpenSSL's own "d2i" functions (and other similar parsing functions) as well as any string whose value has been set with the ASN1_STRING_set() function will additionally NUL terminate the byte array in the ASN1_STRING structure.
- However, it is possible for applications to directly construct valid ASN1_STRING structures which do not NUL terminate the byte array by directly setting the "data" and "length" fields in the ASN1_STRING array. This can also happen by using the ASN1_STRING_set0() function.
- Numerous OpenSSL functions that print ASN.1 data have been found to assume that the ASN1_STRING byte array will be NUL terminated, even though this is not guaranteed for strings that have been directly constructed. Where an application requests an ASN.1 structure to be printed, and where that ASN.1 structure contains ASN1_STRINGs that have been directly constructed by the application without NUL terminating the "data" field, then a read buffer overrun can occur.
- The same thing can also occur during name constraints processing of certificates (for example if a certificate has been directly constructed by the application instead of loading it via the OpenSSL parsing functions, and the certificate contains non NUL terminated ASN1_STRING structures). It can also occur in the X509_get1_email(), X509_REQ_get1_email() and X509_get1_ocsp() functions.
- If a malicious actor can cause an application to directly construct an ASN1_STRING and then process it through one of the affected OpenSSL functions then this issue could be hit. This might result in a crash (causing a Denial of Service attack). It could also result in the disclosure of private memory contents (such as private keys, or sensitive plaintext).
