EUVD-2026-32582

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...

Botan 安全漏洞

Botan is a C++ encryption library developed by Jack Lloyd as an individual project. Versions of Botan prior to 3.12.0 contained security vulnerabilities. These vulnerabilities were caused byBER data, which led to reassembly behavior by the parser, potentially resulting in denial-of-service attack...

SUSE CVE-2026-32884

Botan is a C++ cryptography library. Prior to version 3.11.0, during processing of an X.509 certificate path using name constraints which restrict the set of allowable DNS names, if no subject alternative name is defined in the end-entity certificate Botan would check that the CN was allowed by t...

CVE-2026-32884

A flaw was found in Botan, a C++ cryptography library. During the processing of X.509 certificate paths with DNS name constraints, the library incorrectly handles mixed-case Common Names CN in end-entity certificates that lack a Subject Alternative Name. A remote attacker could exploit this by...

SUSE CVE-2026-34580

Botan is a C++ cryptography library. In 3.11.0, the function CertificateStore::certificateknown had a misleading name; it would return true if any certificate in the store had a DN and subject key identifier, if set matching that of the argument. It did not check that the cert it found and the ce...

SUSE CVE-2026-34582
