botan3: Botan is a C++ cryptography library
CVE-2026-44378 is fixed in botan3 on 1 platform, first by DEBIAN-CVE-2026-44378, released June 24, 2026. It is not reported as exploited. Patch Radar priority: High.
Botan is a C++ cryptography library. Prior to 3.12.0, certain patterns of indefinite length encodings in BER data could cause quadratic behavior in the parser, resulting in a denial of service. Such BER encodings were accepted even in structures which are required to be encoded as DER, which prohibits indefinite length encodings. This vulnerability is fixed in 3.12.0.
