The remote Gentoo host is missing one or more security-related
The remote host is affected by the vulnerability described in GLSA-201503-11
(OpenSSL: Multiple vulnerabilities)
Multiple vulnerabilities have been found in OpenSSL. Please review the
CVE identifiers and the upstream advisory referenced below for details:
RSA silently downgrades to EXPORT_RSA [Client] (Reclassified)
Segmentation fault in ASN1_TYPE_cmp (CVE-2015-0286)
ASN.1 structure reuse memory corruption (CVE-2015-0287)
X509_to_X509_REQ NULL pointer deref (CVE-2015-0288)
PKCS7 NULL pointer dereferences (CVE-2015-0289)
Base64 decode (CVE-2015-0292)
DoS via reachable assert in SSLv2 servers (CVE-2015-0293)
Use After Free following d2i_ECPrivatekey error (CVE-2015-0209)
The following issues affect OpenSSL 1.0.2 only which is not part of the
supported Gentoo stable tree:
OpenSSL 1.0.2 ClientHello sigalgs DoS (CVE-2015-0291)
Multiblock corrupted pointer (CVE-2015-0290)
Segmentation fault in DTLSv1_listen (CVE-2015-0207)
Segmentation fault for invalid PSS parameters (CVE-2015-0208)
Empty CKE with client auth and DHE (CVE-2015-1787)

All OpenSSL 1.0.1 users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose '>=dev-libs/openssl-1.0.1l-r1'
All OpenSSL 0.9.8 users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose '>=dev-libs/openssl-0.9.8z_p5-r1'
Packages which depend on the OpenSSL library need to be restarted for
the upgrade to take effect. Some packages may need to be recompiled.
Tools such as revdep-rebuild may assist in identifying some of these
