CVE-2026-44378 — Botan: Quadratic complexity decoding BER indefinite length encodings

CVE-2026-44378

Botan: Quadratic complexity decoding BER indefinite length encodings PUBLISHED

Description (CNA)

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.
