Fixes:
CVE-2018-12435: requires >= 2.7.0 (NVD extry is incorrect)
"Bug introduced in 2.5.0, fixed in 2.7.0. The 1.10 branch is not affected."
A side channel in the ECDSA signature operation could allow a local attacker to recover the secret key.
CVE-2018-20187: requires >= 2.9.0
"Introduced in 1.11.20, fixed in 2.8.0."
A timing side channel during ECC key generation could leak information about the high bits of the secret scalar. Such information allows an attacker to perform a brute force attack on the key somewhat more efficiently than they would otherwise.
