The remote Gentoo host is missing one or more security-related patches.


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) (CVE-2015-0204) 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) Handshake with unseeded PRNG (CVE-2015-0285) Impact :

A remote attacker can utilize multiple vectors to cause Denial of Service or Information Disclosure.
Workaround :

There is no known workaround at this time.


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 packages.
