New! Vulnerability Priority Rating (VPR)
Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.

SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe remote host is affected by the vulnerability described in GLSA-201203-12 (OpenSSL: Multiple vulnerabilities)
Multiple vulnerabilities have been found in OpenSSL:
Timing differences for decryption are exposed by CBC mode encryption in OpenSSL’s implementation of DTLS (CVE-2011-4108).
A policy check failure can result in a double-free error when X509_V_FLAG_POLICY_CHECK is set (CVE-2011-4109).
Clients and servers using SSL 3.0 handshakes do not clear the block cipher padding, allowing a record to contain up to 15 bytes of uninitialized memory, which could include sensitive information (CVE-2011-4576).
Assertion errors can occur during the handling of malformed X.509 certificates when OpenSSL is built with RFC 3779 support (CVE-2011-4577).
A resource management error can occur when OpenSSL’s server gated cryptography (SGC) does not properly handle handshake restarts (CVE-2011-4619).
Invalid parameters in the GOST block cipher are not properly handled by the GOST ENGINE(CVE-2012-0027).
An incorrect fix for CVE-2011-4108 creates an unspecified vulnerability for DTLS applications using OpenSSL (CVE-2012-0050).
A remote attacker may be able to cause a Denial of Service or obtain sensitive information, including plaintext passwords.
There is no known workaround at this time.
SolutionAll OpenSSL users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=dev-libs/openssl-1.0.0g'
