CVE-2018-9127

CVE-2018-9127 affects Botan library versions 2.2.0–2.4.0; the issue arises from improper wildcard certificate handling, allowing certain certificates to be treated as valid for hostnames under RFC 6125 rules within the same domain. The vulnerability could enable host impersonation if an attacker ...

CVE-2018-9127

Botan 2.2.0 - 2.4.0 fixed in 2.5.0 improperly handled wildcard certificates and could accept certain certificates as valid for hostnames when, under RFC 6125 rules, they should not match. This only affects certificates issued to the same domain as the host, so to impersonate a host one must alrea...

Botan Design Vulnerability

Botan is a library of cryptographic algorithms in the C++ programming language that supports AES, DES, SHA-1, RSA, DSA and Diffie-Hellman. A security vulnerability exists in the RSA implementation in Botan versions prior to 1.10.17, 1.11.x and 2.x prior to 2.3.0. A local attacker can exploit this...

CVE-2017-14737

A cryptographic cache-based side channel in the RSA implementation in Botan before 1.10.17, and 1.11.x and 2.x before 2.3.0, allows a local attacker to recover information about RSA secret keys, as demonstrated by CacheD. This occurs because an array is indexed with bits derived from a secret key...
