Last modified

CVE-2017-14737 is a medium-severity vulnerability rated 5.5/10 on the CVSS scale. 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.. EPSS estimates a 0.32% chance of exploitation in the next 30 days.
