The remote Gentoo host is missing one or more security-related
The remote host is affected by the vulnerability described in GLSA-200912-01
(OpenSSL: Multiple vulnerabilities)
Multiple vulnerabilities have been reported in OpenSSL:
Marsh Ray of PhoneFactor and Martin Rex of SAP independently
reported that the TLS protocol does not properly handle session
renegotiation requests (CVE-2009-3555).
The MD2 hash algorithm is no longer considered to be
cryptographically strong, as demonstrated by Dan Kaminsky. Certificates
using this algorithm are no longer accepted (CVE-2009-2409).
Daniel Mentz and Robin Seggelmann reported the following
vulnerabilities related to DTLS: A use-after-free flaw (CVE-2009-1379)
and a NULL pointer dereference (CVE-2009-1387) in the
dtls1_retrieve_buffered_fragment() function in src/d1_both.c, multiple
memory leaks in the dtls1_process_out_of_seq_message() function in
src/d1_both.c (CVE-2009-1378), and a processing error related to a
large amount of DTLS records with a future epoch in the
dtls1_buffer_record() function in ssl/d1_pkt.c
A remote unauthenticated attacker, acting as a Man in the Middle, could
inject arbitrary plain text into a TLS session, possibly leading to the
ability to send requests as if authenticated as the victim. A remote
attacker could furthermore send specially crafted DTLS packages to a
service using OpenSSL for DTLS support, possibly resulting in a Denial
of Service. Also, a remote attacker might be able to create rogue
certificates, facilitated by a MD2 collision. NOTE: The amount of
computation needed for this attack is still very large.
There is no known workaround at this time.
