  "title": "botan3: Botan is a C\u002B\u002B cryptography library",
  "description": "Botan is a C\u002B\u002B cryptography library. From 2.1.0 until 3.13.0, the Botan C API function botan_block_cipher_block_size converted a size_t block size to int without a bounds check. In an application that accepts external algorithm parameter strings and uses the FFI raw ECB mode, an attacker can select the variable-block-size Lion cipher so that the reported size is truncated, the caller allocates insufficient memory, and later block processing causes memory corruption. The C\u002B\u002B API and normally used C API modes such as CBC and CTR are unaffected. This issue is fixed in version 3.13.0.",
