{"id":"CVE-2026-118765","published":"2026-10-29T17:18:07.523","lastModified":"2026-10-29T21:17:16.967","description":"Botan is a C++ cryptography library. From 3.7.0 until 3.13.0, an application that calls AutoSeeded_RNG::clear() and then calls randomize with an empty output buffer while the generator is unseeded can cause AutoSeeded_RNG to mark itself seeded without consulting the configured entropy source. On builds without BOTAN_HAS_SYSTEM_RNG, the fallback uses only a clock value and process ID, so a later non-empty request can produce output from predictable state. This issue is fixed in version 3.13.0.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":["CWE-335"],"vendors":[],"products":[],"references":[{"url":"https://github.com/randombit/botan/commit/a7389222ace990604b6985add91ee06f55a80c0e","tags":[]},{"url":"https://github.com/randombit/botan/pull/5838","tags":[]},{"url":"https://github.com/randombit/botan/security/advisories/GHSA-95xx-xh9v-v9c4","tags":[]}],"exploitRefs":[{"url":"https://github.com/randombit/botan/commit/a7389222ace990604b6985add91ee06f55a80c0e","tags":[]},{"url":"https://github.com/randombit/botan/pull/5838","tags":[]},{"url":"https://github.com/randombit/botan/security/advisories/GHSA-95xx-xh9v-v9c4","tags":[]}],"hasPoc":true,"ai":null}
