New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

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

Description

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.

Solution

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.
