Randombit Botan Library X509 Certificate Validation Bypass Vulnerability

Summary A programming error exists in a way Randombit Botan cryptographic library version 2.0.1 implements x500 string comparisons which could lead to certificate verification issues and abuse. A specially crafted X509 certificate would need to be delivered to the client or server application in...

Botan X509_Certificate::allowed_usage function design vulnerability

Botan is a cryptographic library written in C++11 and distributed under the Simplified BSD license. A design flaw in the Botan X509Certificate::allowedusage function can be exploited by an attacker to cause some impact on calls with more than one KeyUsage set in the enumeration value...

Botan Security Bypass Vulnerability (CNVD-2017-05578)

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 bypass vulnerability exists in version 1.11.x of Botan prior to 1.11.22, which can be exploited by attackers to obtain sensitive information...

Botan Denial of Service Vulnerability (CNVD-2017-05476)

Botan is a library of cryptographic algorithms in the C++ programming language that supports AES, DES, SHA-1, RSA, DSA and Diffie-Hellman. A denial of service vulnerability exists in versions of Botan prior to 1.11.22, which stems from the program failing to properly validate the path of a...
