The remote Gentoo host is missing one or more security-related
The remote host is affected by the vulnerability described in GLSA-201408-14
(stunnel: Information disclosure)
stunnel does not properly update the state of the pseudo-random
generator after fork-threading which causes subsequent children with the
same process ID to use the same entropy pool. ECDSA and DSA keys, when
not used in deterministic mode (RFC6979), rely on random data for its k
parameter to not leak private key information.
A remote attacker may gain access to private key information from ECDSA
or DSA keys.
There is no known workaround at this time.

All stunnel users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose '>=net-misc/stunnel-5.02'

Medium / CVSS Base Score : 4.3
CVSS Temporal Score : 3.7
