botan2 security update

Type: advisorySource: OSV1 source record

Botan is a BSD-licensed crypto library written in C++. It provides a wide variety of basic cryptographic algorithms, X.509 certificates and CRLs, PKCS \#10 certificate requests, a filter/pipe message processing system, and a wide variety of other features, all written in portable C++. The API reference, tutorial, and examples may help impart the flavor of the library. This is the current stable release branch 2.x of Botan. Security Fix(es): 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.(CVE-2026-44378)
