CVE-2016-8871

CVE-2016-8871 affects Botan 1.11.29 through 1.11.32, where RSA decryption with certain padding options exposes a detectable OAEP timing channel. With a sufficient number of queries, an attacker could recover plaintext. The provided connected documents confirm the vulnerability details but do not ...

CVE-2016-8871

In Botan 1.11.29 through 1.11.32, RSA decryption with certain padding options had a detectable timing channel which could given sufficient queries be used to recover plaintext, aka an "OAEP side channel" attack...

Updated botan packages fix security vulnerabilities

Updated botan packages fix security vulnerabilities: During RSA decryption, how long decoding of PKCS 1 v1.5 padding took was input dependent. If these differences could be measured by an attacker, it could be used to mount a Bleichenbacher million-message attack CVE-2015-7827. ECDSA and DSA...

Botan Downgrade Vulnerability

Botan is a C++ library of cryptographic algorithms that supports AES, DES, SHA-1, RSA, DSA and Diffie-Hellman. A degradation vulnerability exists in Botan versions 1.11.x prior to 1.11.29, which stems from the program's failure to enforce a TLS policy on the signature algorithm and the ECC ellipt...

Botan weak encryption vulnerability

Botan is a C++ library of cryptographic algorithms that supports AES, DES, SHA-1, RSA, DSA and Diffie-Hellman. A weak cryptographic vulnerability in the Miller-Rabin prime test in Botan versions prior to 1.10.8 and 1.11.x prior to 1.11.9 stems from the program failing to properly use a single...

Botan heap buffer overflow vulnerability (CNVD-2016-03251)

Botan is a C++ library of cryptographic algorithms that supports AES, DES, SHA-1, RSA, DSA and Diffie-Hellman. A heap buffer overflow vulnerability exists in the 'P-521' function in Botan version 1.11.x prior to 1.11.27. A remote attacker can exploit this vulnerability to cause a denial of servic...
