The 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).
Impact :
A remote attacker may be able to cause a Denial of Service or obtain sensitive information, including plaintext passwords.
Workaround :
There is no known workaround at this time.
