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...

CVE-2015-7827

CVE-2015-7827 affects Botan cryptographic library: historical versions Bot an 1.10.x prior to 1.10.13 and 1.11.x prior to 1.11.22 are vulnerable. The root cause is a timing side-channel during PKCS#1 padding decoding, enabling remote attackers to mount million-message attacks. Public references i...
