Deskripsi CVE
Botan is a C++ 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++ API and normally used C API modes such as CBC and CTR are unaffected. This issue is fixed in version 3.13.0.

| Nama Kelemahan | Sumber | |
|---|---|---|
| Out-of-bounds Read The product reads data past the end, or before the beginning, of the intended buffer. |
||
| Incorrect Conversion between Numeric Types When converting from one data type to another, such as long to integer, data can be omitted or translated in a way that produces unexpected values. If the resulting values are used in a sensitive context, then dangerous behaviors may occur. |

| Out-of-bounds Write The product writes data past the end, or before the beginning, of the intended buffer. |
