  "title": "Block-size truncation memory corruption in Botan C API",
  "summary": "Botan versions from 2.1.0 before 3.13.0 contain a block-size reporting flaw in the C API. An attacker may cause memory corruption when an application accepts external algorithm selections and uses the raw ECB FFI mode with the Lion cipher. The C++ API and standard C API modes including CBC and CTR are not affected.",
  "mitigation": "Upgrade Botan to version 3.13.0 or later. Until upgrading, avoid raw ECB FFI use with externally controlled algorithm parameters, particularly Lion.",
