Vulnerability CVE-2017-14737
Published: 2017-09-25 Modified: 2017-09-26
| Description: |
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. |
