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...

Fedora 22 : botan (2016-fe0d8f126a)

From the upstream release notes : Botan 1.10.13 has been released backporting some side channel protections for ECDSA signatures CVE-2016-2849 and PKCS 1 RSA decryption CVE-2015-7827. Note that Tenable Network Security has extracted the preceding description block directly from the Fedora update...

MGASA-2016-0208 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 RSA Decryption Vulnerability

Botan is a C++ library of cryptographic algorithms that supports AES, DES, SHA-1, RSA, DSA and Diffie-Hellman. A security vulnerability exists in Botan that allows remote attackers to perform RSA decryption by exploiting the vulnerability to perform a bypass attack...

SSL/TLS: Cross-protocol attack on TLS using SSLv2 (DROWN)

A padding oracle flaw was found in the Secure Sockets Layer version 2.0 SSLv2 protocol. An attacker could potentially use this flaw to decrypt RSA-encrypted cipher text from a connection using a newer SSL/TLS protocol version, allowing them to decrypt such connections. This cross-protocol attack ...
