SynopsisThe remote FreeBSD host is missing one or more security-related
DescriptionThe OpenSSL project reports :
Timing vulnerability in ECDSA signature generation (CVE-2018-0735):
The OpenSSL ECDSA signature algorithm has been shown to be vulnerable
to a timing side channel attack. An attacker could use variations in
the signing algorithm to recover the private key (Low).
Timing vulnerability in DSA signature generation (CVE-2018-0734) :
Avoid a timing attack that leaks information via a side channel that
triggers when a BN is resized. Increasing the size of the BNs prior to
doing anything with them suppresses the attack (Low).
SolutionUpdate the affected packages.
